Dar apie baltus, gudus ir gotus

This paper aims to shed light on the tenacious tendency of would-be philologists and self-taught historians to embellish the history of the Lithuanian nation and its civilization by providing interpretations of ancient texts without real evidence. In particular, the authors review some methodological aspects of historical research in the work of the Lithuanian émigré J. Statkutė de Rosales, Europos šaknys ir mes, lietuviai (The Roots of Europe and We, the Lithuanians). This article points out that her claim that the Goths were the mighty ancestors of today’s Lithuanians derives from a macroscopic misinterpretation and alteration of the only existing text about the origin of the Goths, which is the late Latin Getica, written by Jordanes. Statkutė, who recently received a doctorate honoris causa, identifies the Goths with the ancient Lithuanians by comparing the word Gothi with the Lithuanian ethnonym gudai, and asserts that world historians have intentionally been duped for years by a few deceitful scholars into believing that the Goths originated in Scandinavia. Statkutė holds that the island of Scandza depicted by Jordanes should not be identified with Scandinavia at all, but with the Baltic coast from Eastern Poland to Lithuania.The authors of this paper examine the actual text of Jordanes both philologically and with cross-references to other authors, finding that Statkutė’s conclusions are extremely erroneous. Not only has the Latin text been incorrectly translated by Statkutė in more than one passage, but she has also kept silent – most probably on purpose – about some crucial information, thereby lending support to her theories. The identification of Scandza, the fatherland of the Goths according to Jordanes, with the Baltic coast has to be ruled out mainly by the fact that the Latin historian clearly describes the phenomena of the polar night and midnight sun as being typical of Northern Scandza. Statkutė’s approach to sources written in Latin also appears compromised, not only by leaving out relevant information, but also by her difficulty in understanding (and therefore translating) the texts as well. The authors of this paper point out several other misinterpretations of facts, which are presented in her book as more or less revolutionary findings. In addition, Statkutė’s arrogant accusations against distinguished scholars would be inappropriate even if she were correct in her assumptions. As a matter of fact, her sole merit today is the attempt to arouse Lithuanians’ interest in their own distant past.Straipsnyje vertinama Jūratės Statkutės de Rosales pateikta vėlyvosios Antikos geografo Jordano informacija apie gotus ir Skandzos salą jo darbe „De Getarum sive Gothorum origine et rebus gestis“. Šią salą autorė mėgina lokalizuoti ne kaip Skandinavijos pusiasalį, bet kaip Aistmarių pusiasalį, o pačius salos gyventojus gotus atitinkamai laiko baltų gentimi, ankstesnių tyrinėtojų esą nepagrįstai priskirtą germanams.Patikrinus Jordano tekstus paaiškėjo, kad autorės interpretacija nepagrįsta dėl jos pačios ne visai tiksliai išverstų Jordano tekstų, taip pat dėl nutylėto tekstų tęsinio, kur Jordanas rašo apie salos šiaurinei daliai būdingą poliarinę dieną ir poliarinę naktį.Gotų tapatinimas su gudais nepagrįstas fonetiškai, nes etnonimas ‘gudai’ lotyniškai būtų užrašytas ‘Gudi’ arba ‘Gudae’, bet ne ‘Gothi’.Daroma išvada, kad Jordano aprašytoji Skandzos sala vis dėlto sietina su Skandinavijos pusiasaliu, o gotai buvo viena iš joje gyvenusių germanų genčių. Niekuo nepagrįstas yra ir autorės mėginimas lotynišką Žemaitijos pavadinimą ‘Samogitia’ aiškinti kaip „Žemąją Getiją“ ir taip susieti ją su gotais. Raz jeszcze o pochodzeniu bałtów, gudai i gotówW artykule poddano ocenie informacje na temat Gotów i wyspy Skandza, pochodzące z pracy starożytnego geografa i historyka Jordanesa De Getarum sive Gothorum origine et rebus gestis (O pochodzeniu i czynach Gotów) i wykorzystane przez litewską badaczkę emigracyjną J. Statkutė de Rosales w jej książce Europos šaknys ir mes, lietuviai (Korzenie Europy i my, Litwini). Wyspę tę autorka próbuje identyfikować nie jako Półwysep Skandynawski, a półwysep Zalewu Wiślanego, natomiast mieszkańców tej wyspy – Gotów – odpowiednio uważa za plemię bałtyckie, jej zdaniem niesłusznie zaliczane przez wcześniejszych badaczy do ludów germańskich.Po dokonaniu filologicznej analizy tekstów Jordanesa okazało się, że interpretacja autorki jest nieuzasadniona, ponieważ cytowane przez badaczkę ustępy tekstu zostały przez nią przetłumaczone niezbyt dokładnie, ponadto J. Statkutė de Rosales przemilczała dalsze fragmenty zawierające kluczowe informacje, gdzie Jordanes pisze o charakterystycznym zjawisku występującym w północnej części wyspy, mianowicie o dniu polarnym i nocy polarnej.Utożsamianie Gotów z gudai (etnonim, którym Litwini określali swoich południowo-wschodnich, niekiedy też południowo-zachodnich sąsiadów) jest nieuzasadnione fonetycznie, gdyż etnonim ten po łacinie przybrałby formę gudi lub gudae, ale nie gothi.Z powyższych rozważań można wyciągnąć wniosek, że opisaną przez Jordanesa wyspę Skandza należy jednak wiązać z Półwyspem Skandynawskim, Goci zaś byli jednym z zamieszkujących go plemion germańskich.Niczym nieuzasadniona jest też próba tłumaczenia łacińskiej nazwy Żmudzi (Samogitia) jako „Dolnej Getii” i takim sposobem związania jej z Gotami.SŁOWA KLUCZOWE: Goci, gudai, Skandynawia, Statkutė de Rosales, Jordanes, Prätorius, pseudoteorie

Standalone vertex finding in the ATLAS muon spectrometer

A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to bbar b final states, and pp collision data at √s = 7 TeV collected with the ATLAS detector at the LHC during 2011

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson

Measurement of the top quark pair cross section with ATLAS in pp collisions at √s=7 TeV using final states with an electron or a muon and a hadronically decaying τ lepton

A measurement of the cross section of top quark pair production in proton-proton collisions recorded with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 7 TeV is reported. The data sample used corresponds to an integrated luminosity of 2.05 fb -1. Events with an isolated electron or muon and a τ lepton decaying hadronically are used. In addition, a large missing transverse momentum and two or more energetic jets are required. At least one of the jets must be identified as originating from a b quark. The measured cross section, σtt-=186±13(stat.)±20(syst.)±7(lumi.) pb, is in good agreement with the Standard Model prediction

Measurement of the top quark-pair production cross section with ATLAS in pp collisions at \sqrt{s}=7\TeV

A measurement of the production cross-section for top quark pairs(\ttbar) in $pp$ collisions at \sqrt{s}=7 \TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider. Events are selected in two different topologies: single lepton (electron $e$ or muon $\mu$) with large missing transverse energy and at least four jets, and dilepton ($ee$, $\mu\mu$ or $e\mu$) with large missing transverse energy and at least two jets. In a data sample of 2.9 pb-1, 37 candidate events are observed in the single-lepton topology and 9 events in the dilepton topology. The corresponding expected backgrounds from non-\ttbar Standard Model processes are estimated using data-driven methods and determined to be $12.2 \pm 3.9$ events and $2.5 \pm 0.6$ events, respectively. The kinematic properties of the selected events are consistent with SM \ttbar production. The inclusive top quark pair production cross-section is measured to be \sigmattbar=145 \pm 31 ^{+42}_{-27} pb where the first uncertainty is statistical and the second systematic. The measurement agrees with perturbative QCD calculations.Comment: 30 pages plus author list (50 pages total), 9 figures, 11 tables, CERN-PH number and final journal adde

Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7 fb−1 of √s=7 TeV proton-proton collisions

Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb−1 of pp collision data at s√=7TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from ≥6 to ≥9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m 0, gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV

Measurement of the top quark pair production cross-section with ATLAS in the single lepton channel

A measurement of the production cross-section for top quark pairs (t[bar over t]) in pp collisions at √s = 7 TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider. Events are selected in the single lepton topology by requiring an electron or muon, large missing transverse momentum and at least three jets. With a data sample of 35 pb[superscript −1], two different multivariate methods, one of which uses b-quark jet identification while the other does not, use kinematic variables to obtain cross-section measurements of σ[subscript t bar over t] = 187 ± 11 (stat.) [+18 over −17] (syst.) ± 6 (lumi.) pb and σ[subscript t bar over t] = 173 ± 17 (stat.) [+18 over −16] (syst.) ±6 (lumi.) pb respectively. The two measurements are in agreement with each other and with QCD calculations. The first measurement has a better a priori sensitivity and constitutes the main result of this Letter.European Organization for Nuclear ResearchUnited States.

Search for anomalous production of prompt like-sign muon pairs and constraints on physics beyond the standard model with the ATLAS detector

Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración, si le hubiere, y los autores pertenecientes a la UAMAn inclusive search for anomalous production of two prompt, isolated muons with the same electric charge is presented. The search is performed in a data sample corresponding to 1.6 fb-1 of integrated luminosity collected in 2011 at √s = 7 TeV with the ATLAS detector at the LHC. Muon pairs are selected by requiring two isolated muons of the same electric charge with pT > 20 GeV and |η| < 2.5. Minimal requirements are placed on the rest of the event activity. The distribution of the invariant mass of the muon pair m(μμ) is found to agree well with the background expectation. Upper limits on the cross section for anomalous production of two muons with the same electric charge are placed as a function of m(μμ) within a fiducial region defined by the event selection. The fiducial cross-section limit constrains the like-sign top-quark pair-production cross section to be below 3.7 pb at 95% confidence level. The data are also analyzed to search for a narrow like-sign dimuon resonance as predicted for e.g. doubly charged Higgs bosons (H±±). Assuming pair production of H±± bosons and a branching ratio to muons of 100% (33%), this analysis excludes masses below 355 (244) GeV and 251 (209) GeV for H±± bosons coupling to left-handed and right-handed fermions, respectivelyWe acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; CONICYT, Chile; CAS, MOST and NSFC, China; COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic; DNRF, DNSRC and Lundbeck Foundation, Denmark; ARTEMIS, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNAS, Georgia; BMBF, DFG, HGF, MPG and AvH Foundation, Germany; GSRT, Greece; ISF, MINERVA, GIF, DIP and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; FOM and NWO, Netherlands; RCN, Norway; MNiSW, Poland; GRICES and FCT, Portugal; MERYS (MECTS), Romania; MES of Russia and ROSATOM, Russian Federation; JINR; MSTD, Serbia; MSSR, Slovakia; ARRS and MVZT, Slovenia; DST/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SER, SNSF and Cantons of Bern and Geneva, Switzerland; NSC, Taiwan; TAEK, Turkey; STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America.

Study of jets produced in association with a W boson in pp collisions at s√=7 TeV with the ATLAS detector

We report a study of final states containing a W boson and hadronic jets, produced in proton-proton collisions at a center-of-mass energy of 7 TeV. The data were collected with the ATLAS detector at the CERN LHC and comprise the full 2010 data sample of 36 pb(-1). Cross sections are determined using both the electron and muon decay modes of the W boson and are presented as a function of inclusive jet multiplicity, N-jet, for up to five jets. At each multiplicity, cross sections are presented as a function of jet transverse momentum, the scalar sum of the transverse momenta of the charged lepton, missing transverse momentum, and all jets, the invariant mass spectra of jets, and the rapidity distributions of various combinations of leptons and final-state jets. The results, corrected for all detector effects and for all backgrounds such as diboson and top quark pair production, are compared with particle-level predictions from perturbative QCD. Leading-order multiparton event generators, normalized to the next-to-next-to-leading-order total cross section for inclusive W-boson production, describe the data reasonably well for all measured inclusive jet multiplicities. Next-to-leading-order calculations from MCFM, studied here for N-jet <= 2, and BLACKHAT-SHERPA, studied here for N-jet <= 4, are found to be mostly in good agreement with the data

The HADES RV programme with HARPS-N at TNG. XI. GJ 685 b: a warm super-Earth around an active M dwarf

Context. Small rocky planets seem to be very abundant around low-mass M-type stars. Their actual planetary population is however not yet precisely understood. Currently, several surveys aim to expand the statistics with intensive detection campaigns, both photometric and spectroscopic. Aims: The HADES program aims to improve the current statistics through the in-depth analysis of accurate radial-velocity (RV) monitoring in a narrow range of spectral sub-types, with the precision needed to detect small planets with a few Earth masses. Methods: We analyse 106 spectroscopic HARPS-N observations of the active M0-type star GJ 685 taken over the past five years. We combine these data with photometric measurements from different observatories to accurately model the stellar rotation and disentangle its signals from genuine Doppler planetary signals in the RV data. We run an MCMC analysis on the RV and activity index time series to model the planetary and stellar signals present in the data, applying Gaussian Process regression technique to deal with the stellar activity signals. Results: We identify three periodic signals in the RV time series, with periods of 9, 24, and 18 d. Combining the analyses of the photometry of the star with the activity indexes derived from the HARPS-N spectra, we identify the 18 d and 9 d signals as activity-related, corresponding to the stellar rotation period and its first harmonic, respectively. The 24 d signal shows no relation to any activity proxy, and therefore we identify it as a genuine planetary signal. We find the best-fit model describing the Doppler signal of the newly found planet, GJ 685 b, corresponding to an orbital period Pb = 24.160-0.047+0.061 d and a minimum mass MP sin i = 9.0-1.8+1.7 M⊕. We also study a sample of 70 RV-detected M-dwarf planets, and present new statistical evidence of a difference in mass distribution between the populations of single- and multi-planet systems, which can shed new light on the formation mechanisms of low-mass planets around late-type stars.
