Search for pair and single production of new heavy quarks that decay to a Z boson and a third-generation quark in pp collisions at s = 8 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search is presented for the production of new heavy quarks that decay to a Z boson and a third-generation Standard Model quark. In the case of a new charge +2/3 quark (T ), the decay targeted is T Zt, while the decay targeted for a new charge 1/3 quark(B) is B Zb. The search is performed with a dataset corresponding to 20.3 fb1 of pp collisions at s=8 TeV recorded in 2012 with the ATLAS detector at the CERN Large Hadron Collider. Selected events contain a high transverse momentum Z boson candidate reconstructed from a pair of oppositely charged same-flavor leptons (electrons or muons), and are analyzed in two channels defined by the absence or presence of a third lepton. Hadronic jets, in particular those with properties consistent with the decay ofa b-hadron, are also required to be present in selected events.
