Search for pair production of heavy vectorlike quarks decaying into hadronic final states in pp collisions at √s=13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search is presented for the pair production of heavy vector-like quarks, TT¯ or BB¯, that decay into final states with jets and no reconstructed leptons. Jets in the final state are classified using a deep neural network as arising from hadronically decaying W/Z bosons, Higgs bosons, top quarks, or background. The analysis uses data from the ATLAS experiment corresponding to 36.1 fb−1 of proton-proton collisions with a center-of-mass energy of √s=13 TeV delivered by the Large Hadron Collider in 2015 and 2016. No significant deviation from the Standard Model expectation is observed. Results are interpreted assuming the vector-like quarks decay into a Standard Model boson and a third-generation-quark, T→Wb,Ht,Zt or B→Wt,Hb,Zb, for a variety of branching ratios. At 95% confidence level, the observed (expected) lower limit on the vector-like B-quark mass for a weak-isospin doublet (B,Y) is 950 (890) GeV
