Název v původním jazyce

Search for single production of vector-like quarks decaying into W(ℓν)b in pp collisions at √s=13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for single production of a vector-like quark Q, which could be either a singlet T, with charge 2/3​, or a Y from a (T, B, Y) triplet, with charge −4/3​, is performed using data from proton-proton collisions at a centre-of-mass energy of 13 TeV. The data correspond to the full integrated luminosity of 140 fb−1 recorded with the ATLAS detector during Run 2 of the Large Hadron Collider. The analysis targets Q → Wb decays where the W boson decays leptonically. The data are found to be consistent with the expected Standard Model background, so upper limits are set on the cross-section times branching ratio, and on the coupling of the Q to the Standard Model sector for these two benchmark models. Effects of interference with the Standard Model background are taken into account. For the singlet T, the 95% confidence level limit on the coupling strength κ ranges between 0.22 and 0.52 for masses from 1150 to 2300 GeV. For the (T, B, Y) triplet, the limits on κ vary from 0.14 to 0.46 for masses from 1150 to 2600 GeV.
