The leptoquark Hunter’s guide: large coupling

Leptoquarks have recently received much attention especially because they may provide an explanation to the RD(∗) and RK(∗) anomalies in rare B meson decays. In a previous paper we proposed a systematic search strategy for all possible leptoquark flavors by focusing on leptoquark pair production. In this paper, we extend this strategy to large (order unity) leptoquark couplings which offer new search opportunities: single leptoquark production and t-channel leptoquark exchange with dilepton final states. We discuss the unique features of the different search channels and show that they cover complementary regions of parameter space. We collect and update all currently available bounds for the…
