Event activity dependence of Υ(nS) production in √sNN = 5.02 TeV pPb and √s = 2.76 TeV pp collisions

Abstract: The production of Y(1S), Y(2S), and Y(3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities of about 31 inverse nanobarns (pPb) and 5.4 inverse picobarns (pp), collected in 2013 by the CMS experiment at the LHC. Upsilons that decay into muons are reconstructed within the rapidity interval abs(y[CM]) , are found to rise with both measures of the event activity in pp and pPb. In both collision systems, the ratios of the excited to the ground state cross sections, Y(nS)/Y(1S), are found to decrease with the charged-particle multiplicity, while as a function of the transverse energy the variation is less pronounced. The event activity integrated double ratios, [Y(nS)/Y(1S)][pPb] / [Y(nS)/Y(1S)][pp], are also measured and found to be 0.83 +/- 0.05 (stat.) +/- 0.05 (syst.) and 0.71 +/- 0.08 (stat.) +/- 0.09 (syst.) for Y(2S) and Y(3S), respectively.

Formação de profissionais de saúde no Brasil: uma análise no período de 1991 a 2008

Abstract: Estudo conduzido com o objetivo de contribuir para o planejamento e implementacao de politicas de qualificacao profissional no campo da saude. Foram analisados 14 cursos de graduacao da area da saude: biomedicina, ciencias biologicas, educacao fisica, enfermagem, farmacia, fisioterapia, fonoaudiologia, medicina, medicina veterinaria, nutricao, odontologia, psicologia, servico social e terapia ocupacional, no periodo de 1991 a 2008. Dados sobre numero de ingressantes, taxa de ocupacao de vagas, distribuicao de concluintes por habitante, genero e renda familiar foram coletados a partir dos bancos do Ministerio da Educacao. Para o curso de medicina, a relacao foi de 40 candidatos por vaga nas instituicoes publicas contra 10 nas privadas. A maioria dos ingressantes era composta por mulheres. A regiao Sudeste concentrou 57% dos concluintes, corroborando o desequilibrio de distribuicao regional das oportunidades de formacao de profissionais de saude e indicando a necessidade de politicas de incentivo a reducao dessas desigualdades.

Search for the Standard Model Higgs Boson in the Decay Channel H→ZZ→4l in pp Collisions at √s=7 TeV

Abstract: A search for a Higgs boson in the four-lepton decay channel H→ZZ, with each Z boson decaying to an electron or muon pair, is reported. The search covers Higgs boson mass hypotheses in the range of 110 100 GeV (with 13 below 160 GeV), while 67.1±6.0 (9.5±1.3) events are expected from background. The four-lepton mass distribution is consistent with the expectation of standard model background production of ZZ pairs. Upper limits at 95% confidence level exclude the standard model Higgs boson in the ranges of 134–158 GeV, 180–305 GeV, and 340–465 GeV. Small excesses of events are observed around masses of 119, 126, and 320 GeV, making the observed limits weaker than expected in the absence of a signal.
