Multiple identities in decentralized Spain: The case of Catalonia

Publicado en Regional and Federal Studies, vol. 8, nº 3, 1998, pp. 65-88.The persistence of a dual self-identification expressed by citizens in the Spanish Comunidades Autónomas (nationalities and regions) is one of the main features of centre-periphery relations in democratic Spain. This 'dual identity' or 'compound nationality' incorporates -in variable proportions, individually or subjectively asserted- both state/national and ethnoterritorial identities with no apparent exclusion. It characterises the ambivalent and dynamic nature of spatial politics in decentralized Spain. A succinct review of the main developments in Spain's contemporary history is carried out in order to provide a background for the discussion of the various identities expressed by citizens in Catalonia. A segmentation analysis reviews the various forms of Catalan self-identification, among which ‘duality’ is to be underlined.Peer reviewe

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Search for pair-produced resonances decaying to jet pairs in proton-proton collisions at √s=8 TeV

Results are reported of a general search for pair production of heavy resonances decaying to pairs of hadronic jets in events with at least four jets. The study is based on up to 19.4 fb(-1) of integrated luminosity from proton-proton collisions at a center-of-mass energy of 8 TeV, recorded with the CMS detector at the LHC. Limits are determined on the production of scalar top quarks (top squarks) in the framework of R-parity violating supersymmetry and on the production of color-octet vector bosons (colorons). First limits at the LHC are placed on top squark production for two scenarios. The first assumes decay to a bottom quark and a light-flavor quark and is excluded for masses between 200 and 385 GeV, and the second assumes decay to a pair of light-flavor quarks and is excluded for masses between 200 and 350 GeV at 95% confidence level. Previous limits on colorons decaying to light-flavor quarks are extended to exclude masses from 200 to 835 GeV

Measurement of the sum ofWW and WZ production with W+dijet events in pp collisions at √ s = 7 TeV

A measurement of the inclusive WW+WZ diboson production cross section in proton–proton collisions is reported, based on events containing a leptonically decaying √W boson and exactly two jets. The data sample, collected at s = 7 TeV with the CMS detector at the LHC, corresponds to an integrated luminosity of 5.0 fb−1. The measured value of the sum of the inclusive WW and WZ cross sections is σ(pp → WW + WZ) = 68.9 ± 8.7 (stat.) ± 9.7 (syst.) ± 1.5 (lum.) pb, consistent with the standard model prediction of 65.6±2.2 pb. This is the first measurement of WW+WZ production in pp collisions using this signature. No evidence for anomalous triple gauge couplings is found and upper limits are set on their magnitudes

Search for Pair Production of Third-Generation Leptoquarks and Top Squarks in pp Collisions at √s=7 TeV

Results are presented from a search for the pair production of third-generation scalar and vector leptoquarks, as well as for top squarks in R-parity-violating supersymmetric models. In either scenario, the new, heavy particle decays into a τ lepton and a b quark. The search is based on a data sample of pp collisions at √s=7  TeV, which is collected by the CMS detector at the LHC and corresponds to an integrated luminosity of 4.8  fb[superscript -1]. The number of observed events is found to be in agreement with the standard model prediction, and exclusion limits on mass parameters are obtained at the 95% confidence level. Vector leptoquarks with masses below 760 GeV are excluded and, if the branching fraction of the scalar leptoquark decay to a τ lepton and a b quark is assumed to be unity, third-generation scalar leptoquarks with masses below 525 GeV are ruled out. Top squarks with masses below 453 GeV are excluded for a typical benchmark scenario, and limits on the coupling between the top squark, τ lepton, and b quark, λ333′ are obtained. These results are the most stringent for these scenarios to date

Measurement of the underlying event activity in pp collisions at √s = 0.9 and 7 TeV with the novel jet-area/median approach

Open Access: This article is distributed under the terms of the Creative Commons Attribution License.-- Chatrchyan, S. et al.The first measurement of the charged component of the underlying event using the novel >jet-area/median> approach is presented for proton-proton collisions at centre-of-mass energies of 0.9 and 7 TeV. The data were recorded in 2010 with the CMS experiment at the LHC. A new observable, sensitive to soft particle production, is introduced and investigated inclusively and as a function of the event scale defined by the transverse momentum of the leading jet. Various phenomenological models are compared to data, with and without corrections for detector effects. None of the examined models describe the data satisfactorily. © 2012 SISSA.Acknowledge support from BMWF and FWF (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); MoER, SF0690030s09 and ERDF (Estonia); Academy of Finland, MEC, and HIP (Finland); CEA and CNRS/IN2P3 (France);BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF and WCU (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); MSI (New Zealand); PAEC (Pakistan); MSHE and NSC (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MON, RosAtom, RAS and RFBR (Russia); MSTD (Serbia); SEIDI and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); ThEP, IPST and NECTEC (Thailand); TUBITAK and TAEK (Turkey); NASU (Ukraine); STFC (United Kingdom); DOE and NSF (USA).

Measurements of jet multiplicity and differential production cross sections of Z+jets events in proton-proton collisions at sqrt(s)=7TeV

Measurements of differential cross sections are presented for the production of a Z boson and at least one hadronic jet in proton-proton collisions at root s = 7 TeV, recorded by the CMS detector, using a data sample corresponding to an integrated luminosity of 4.9 fb(-1). The jet multiplicity distribution is measured for up to six jets. The differential cross sections are measured as a function of jet transverse momentum and pseudorapidity for the four highest transverse momentum jets. The distribution of the scalar sum of jet transverse momenta is also measured as a function of the jet multiplicity. The measurements are compared with theoretical predictions at leading and next-to-leading order in perturbative QCD.Austrian Federal Ministry of Science, Research and EconomyAustrian Science FundBelgian Fonds de la Recherche ScientifiqueFonds voor Wetenschappelijk OnderzoekConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Bulgarian Ministry of Education and ScienceCERNChinese Academy of SciencesMinistry of Science and TechnologyNational Natural ScienceFoundationofChinaColombian FundingAgency (COLCIENCIAS)Croatian Ministry of Science, Education, and SportCroatian Science FoundationResearch Promotion Foundation, CyprusMinistry of Education and Research, EstoniaEstonian Research Council, EstoniaEuropean Regional Development Fund, EstoniaAcademy of FinlandFinnish Ministry of Education and CultureHelsinki Institute of PhysicsInstitut National de Physique Nucleaire et de Physique des Particules / CNRS, FranceCommissariat a l'Energie Atomique et aux Energies Alternatives / CEA, FranceBundesministerium fur Bildung und Forschung, GermanyDeutsche Forschungsgemeinschaft, GermanyHelmholtz-Gemeinschaft Deutscher Forschungs zentren, GermanyGeneral Secretariat for Research and Technology, GreeceNational Scientific Research Foundation, HungaryNational Innovation Office, HungaryDepartment of Atomic Energy, IndiaDepartment of Science and Technology, IndiaInstitute for Studies in Theoretical Physics and Mathematics, IranScience Foundation, IrelandIstituto Nazionale di Fisica Nucleare, ItalyKorean Ministry of Education, Science and Technology, Republic of KoreaWorld Class University program of NRF, Republic of KoreaLithuanian Academy of SciencesMinistry of Education, and University of Malaya (Malaysia)Mexican Funding Agency (CINVESTAV)Mexican Funding Agency (CONACYT)Mexican Funding Agency (SEP)Mexican Funding Agency (UASLP-FAI)Ministry of Business, Innovation and Employment, New ZealandPakistan Atomic Energy CommissionMinistry of Science and Higher Education, PolandNational Science Centre, PolandFundacao para a Cienciaea Tecnologia, PortugalJINR, DubnaMinistry of Education and Science of the Russian FederationFederal Agency of Atomic Energy of the Russian FederationRussian Academy of SciencesRussian Foundation for Basic ResearchMinistry of Education, Science and Technological Development of SerbiaSecretaria de Estado de Investigacion, Desarrollo e Innovacion and Programa Consolider-Ingenio, SpainSwiss Funding Agency (ETH Board)Swiss Funding Agency (ETH Zurich)Swiss Funding Agency (PSI)Swiss Funding Agency (SNF)Swiss Funding Agency (UniZH)Swiss Funding Agency (Canton Zurich)Swiss Funding Agency (SER)Ministry of Science and Technology, TaipeiThailand Center of Excellence in PhysicsInstitute for the Promotion of Teaching Science andTechnologyofThailandSpecialTaskForceforActivating ResearchNational Science and Technology Development Agency of ThailandScientific and Technical Research Council of TurkeyTurkish Atomic Energy AuthorityNational Academy of Sciences of Ukraine, UkraineState Fund for Fundamental Researches, UkraineScience and Technology Facilities Council, United KingdomU.S. Department of EnergyU.S. National Science FoundationMarie Curie programEuropean Research CouncilEPLANET (European Union)Leventis FoundationA.

Search for anomalous production of events with three or more leptons in pp collisions at √s = 8TeV

Published by the American Physical Society under the terms of the Creative Commons Attribution 3.0 License. Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.A search for physics beyond the standard model in events with at least three leptons is presented. The data sample, corresponding to an integrated luminosity of 19.5fb-1 of proton-proton collisions with center-of-mass energy s=8TeV, was collected by the CMS experiment at the LHC during 2012. The data are divided into exclusive categories based on the number of leptons and their flavor, the presence or absence of an opposite-sign, same-flavor lepton pair (OSSF), the invariant mass of the OSSF pair, the presence or absence of a tagged bottom-quark jet, the number of identified hadronically decaying τ leptons, and the magnitude of the missing transverse energy and of the scalar sum of jet transverse momenta. The numbers of observed events are found to be consistent with the expected numbers from standard model processes, and limits are placed on new-physics scenarios that yield multilepton final states. In particular, scenarios that predict Higgs boson production in the context of supersymmetric decay chains are examined. We also place a 95% confidence level upper limit of 1.3% on the branching fraction for the decay of a top quark to a charm quark and a Higgs boson (t→cH), which translates to a bound on the left- and right-handed top-charm flavor-violating Higgs Yukawa couplings, λtcH and λctH, respectively, of |λtcH|2+|λctH|2<0.21
