RODAS DE CONVERSA NA BIBLIOTECA: EXPERIÊNCIA DO INSTITUTO FEDERAL FARROUPILHA CAMPUS SÃO VICENTE DO SUL-RS

Busca-se refletir acerca da realização da ação cultural denominada Rodas de conversa, dentro do espaço da biblioteca Instituto Federal Farroupilha Campus São Vicente do Sul-RS, como um mecanismo de inclusão social. A biblioteca enquanto ambiente democrático desempenha uma função fundamental para o desenvolvimento do trabalho pedagógico e das estratégias educacionais da escola contribuindo para o ensino, cultura e cidadania. A partir do trabalho realizado, foi possível perceber não só a ampliação das atividades básicas em uma biblioteca, como também um forma de inclusão social

Search for single production of vector-like quarks decaying to a Z boson and a top or a bottom quark in proton-proton collisions at √s=13 TeV

© 2017, The Author(s).A search for single production of vector-like quarks, T and B, decaying into a Z boson and a top or a bottom quark, respectively, is presented. The search is performed using data collected by the CMS experiment at the LHC in proton-proton collisions at s=13 TeV, corresponding to an integrated luminosity of 2.3fb−1. An exotic T quark production mode through the decay of a heavy Z′ resonance is also considered. The search is performed in events with a Z boson decaying leptonically, accompanied by a bottom or a top quark decaying hadronically. No excess of events is observed over the standard model background expectation. Products of production cross section and branching fraction for T and B quarks from 1.26 and 0.13 pb are excluded at 95% confidence level for the range of resonance mass considered, which is between 0.7 and 1.7 TeV. Limits on the product of the Z′ boson production cross section and branching fraction, with the Z′ boson decaying to the Tt final state, are set between 0.31 and 0.13 pb, for Z′ boson masses in the range from 1.5 to 2.5 TeV. This is the first search at 13 TeV for single production of vector-like quarks in events with a Z boson decaying leptonically accompanied by boosted jets.[Figure not available: see fulltext.]

Search for single production of vector-like quarks decaying to a Z boson and a top or a bottom quark in proton-proton collisions at sqrt(s)=13 TeV

The search is performed using data collected by the CMS experiment at the LHC in proton-proton collisions at s=13 TeV, corresponding to an integrated luminosity of 2.3fbâ\u88\u921. An exotic T quark production mode through the decay of a heavy Zâ\u80² resonance is also considered. The search is performed in events with a Z boson decaying leptonically, accompanied by a bottom or a top quark decaying hadronically.
