Searching for the single production of vector-like quarks in the Wb final state with the ATLAS detector at 13TeV — •Ferdinand Schenck1, Francesco Peri1, Anjishnu Bandyopadhyay2, Janet Dietrich1, Heiko Lacker1, and Ian Brock2 — 1Humboldt-Universität zu Berlin — 2Rheinische Friedrich-Wilhelms-Universität Bonn
This talk will cover the results from an ATLAS search for the single production vector-like T2/3 or Y4/3 quarks decaying to a Wb final state using 36.1 fb−1 of proton-proton data collected at 13TeV by the ATLAS experiment, as well as a new search aiming to expand upon these results.
The initial search focused exclusively on a 1-lepton final state, while the new search aims to improve on this by the addition of a 0-lepton final state, the use of approximately 140 fb−1 of data, as well as by the addition of Machine Learning based discriminants and taggers.
