LA VILLA BAJOIMPERIAL Y TARDO ANTIGUA DE LOS MONDRAGONES (GRANADA)

The villa of Mondragones is an unpublished archaeological site located in the north of Granada, very closed to the ancient Municipium Florentinum Iliberritanum, and it is part of its ager. It is a very  vast settlement  where it’s easy to identify  the principal  elements  of a villa, as the domus, the pars fructuaria and pars rustica. The site has been occupied from the f irst century A.D.  to the  seventh  century  A.D.,  that  let  us analyze  the  changes  occurred  from  the  fourth century A.D. in the hinterland  of Eliberri.La villa de los Mondragones es un yacimiento arqueológico inédito que se localiza en la zona norte  de Granada,  muy  cerca  del  antiguo  Municipium Florentinum Iliberritanum,  formando parte de su  ager.  Se trata de un asentamiento  de gran extensión  en el que se identif ican los elementos fundamentales de una villa, como son la domus, la pars fructuaria y elementos de la pars rustica. Tiene  un periodo  de  ocupación  que va desde  su fundación  en el siglo I d.C. hasta el siglo VII d.C. lo cual permite analizar los cambios producidos a partir del siglo IV d.C. y las transformaciones  de la Antigüedad  Tardía en el  territorio  más próximo  a la ciudad de Eliberri

A mid-third millennium BC collective burial cave in central iberia: El Rebollosillo (Torrelaguna, Madrid)

[EN] El Rebollosillo is a small karstic cave located in the center of Iberia used for the disposition of secondary burials during the mid third millennium BC. We present bioanthropological, isotopic (87Sr/86Sr, δ 13C y δ 18O) analyses and 16 radiocarbon dates on human remains, as well as mineralogical characterization of 6 beads (4 of them variscite from Palazuelo de las Cuevas, Zamora), and a quantitative analysis of 43 pottery fragments recovered during the 1989 excavations. A minimum of 21 individuals have been identified, covering all age ranges and sex. Low percentages of pathologies have been detected, mainly dental calculus and caries, with specific cases of cribra orbitalia, periostosis and arthritis. Only adults received a clearly individualized treatment, suggestive of achieved status. We interpret the evidence as a multi-staged mortuary program, the last phase of which is documented at the site, with previous stages perhaps carried out elsewhere, and we evaluate these results in the context of the regional funerary record.[ES] El Rebollosillo es una pequeña cueva kárstica situada en el centro de la Península Ibérica utilizada para la disposición de enterramientos secundarios en la mitad del III milenio AC. Presentamos resultados bioantropológicos, isotópicos (87Sr/86Sr, δ13C y δ18O) y 16 dataciones radiocarbónicas de los restos humanos, una descripción cuantificada de los 43 fragmentos cerámicos y de caracterización mineralógica de 6 cuentas recuperadas durante la excavación de 1989, cuatro de las cuales probablemente proceden de Palazuelo de las Cuevas (Zamora). El análisis bioantropológico indica un mínimo de 21 individuos con todos los rangos de edad y sexo. Se han detectado bajos porcentajes de patologías, mayoritariamente cálculo dental y caries, con casos puntuales de cribra orbitalia, periostosis y artrosis. La disposición de los restos sugiere que sólo los adultos recibieron un tratamiento claramente individualizado, quizás acorde con un estatus adquirido con la edad. Proponemos que el registro representa la última fase de un programa mortuorio cuyas etapas previas debieron desarrollarse en otros lugares y valoramos estos resultados en el contexto del registro funerario regional.Peer Reviewe

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The second-order Fourier coefficients (v(2)) characterizing the azimuthal distributions of Y(1S) and Y(2S) mesons produced in PbPb collisions at root s(NN) = 5.02 TeV are studied. The Y mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb(-1). The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range vertical bar y vertical bar < 2.4, in the transverse momentum interval 0 < pT < 50 GeV/c, and in three centrality ranges of 10-30%, 30-50% and 50-90%. In contrast to the J/psi mesons, the measured v(2) values for the Y mesons are found to be consistent with zero. (C) 2021 The Author(s). Published by Elsevier B.V.Peer reviewe
