Single production of vectorlike Y quarks at the HL-LHC

We study single production of exotic vectorlike Y quark with electric charge |QY|=4/3 and its subsequent decay at the High Luminosity LHC (HL-LHC). Most of the vector like quark (VLQ) decays have the electroweak W bosons in the intermediate state. Besides their direct productions singly or pairs, th...
