Searching for single production of vector-like quarks decaying into Wb at a future muon-proton collider

Abstract

In this work, we investigate the single production of the Vector-Like Quarks (VLQs) T and Y, with charge +2/3e and −4/3e, respectively, both decaying into Wb at a future μp collider with s√=5.29,6.48, and 9.16 TeV. We focus on two final states, where the W boson decays leptonically or hadronically (in the latter case, it is highly boosted, leading to a fat W-jet). By performing a detailed signal-to-background analysis in presence of detector simulations, the 5σ discovery prospects and 95\% CL exclusion limits are mapped over parameter space regions of the model accommodating such new heavy quarks, assuming an integrated luminosity of 100 fb−1 at each of the aforementioned energies.
