Search for single vector-like B quark production and decay via B RIGHTWARDS ARROW bH(bb/bar/) in pp collisions at CMS = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search is presented for single production of a vector-like B quark decaying into a Standard Model b-quark and a Standard Model Higgs boson, which decays intoa b-b pair. The search is carried out in 139 fb-1 of SQUARE ROOTs = 13TeV proton-proton collisiondata collected by the ATLAS detector at the LHC between 2015 and 2018. No significantdeviation from the Standard Model background prediction is observed, and mass-dependentexclusion limits at the 95% confidence level are set on the resonance production cross-sectionin several theoretical scenarios determined by the couplings cW, cZ and cH between theB quark and the Standard Model W, Z and Higgs bosons, respectively. For a vector-likeB occurring as an isospin singlet, the search excludes values of cW greater than 0.45 for aB resonance mass (mB) between 1.0 and 1.2TeV. For 1.2TeV &lt; mB &lt; 2.0TeV, cW valueslarger than 0.50-0.65 are excluded. If the B occurs as part of a (B, Y ) doublet, the smallestexcluded cZ coupling values range between 0.3 and 0.5 across the investigated resonance mass range 1.0TeV &lt; mB &lt; 2.0TeV.
