Search for single production of vector-like quarks using boosted techniques with the ATLAS detector — •Anjishnu Bandyopadhyay1, Ian Brock1, Janet Dietrich2, Heiko Lacker2, and Ferdinand Schenck21University of Bonn — 2Humboldt University Berlin

Vector-like quarks are hypothetical spin 1/2 fermions predicted by various Beyond the Standard Model (BSM) theories. A search for Y4/3 and T2/3 is performed. The search is conducted in the Wb decay mode. In addition to the semi-leptonic final state, a search in the fully hadronic final state is also performed using the full Run 2 dataset (140 fb−1) collected by the ATLAS detector. This talk will focus on boosted techniques, one of them being boosted taggers, used in analysing the hadronic final state of ppY/TWb.
