Mono Vector-Quark Production at the LHC

Vector-like quark is a common feature in many new physics models. We study the vector-like quark production as an s-channel resonance at the Large Hadron Collider for the vector-like quarks mainly mixing with the top- and bottom-quark in the Standard Model. We emphasize that the leptonic angular distribution can be used to discriminate various vector-like quark models.
