We study implications of large lepton-quark-leptoquark couplings for direct leptoquark searches at Large Hadron Collider. present all existing flavor constraints on the strength these assuming that leptoquarks under consideration interact exclusively with charged leptons and quarks same generation. find can have sizeable to Standard Model fermions. This insures a self consistency our study. discuss production mechanisms LHC demonstrate importance inclusion t-channel pair and, in particular, single through recast an CMS search second generation leptoquark.
