Abstract
We analyze the signatures of new physics scenarios featuring third-family quark-lepton unification
at the TeV scale in lepton-quark fusion at hadron colliders. Working with complete UV dynamics
based on the SU(4) gauge symmetry in the third-family fermions, we simulate the resonant production of a vector leptoquark at the next-to-leading order, including its decay and matching to the
parton showers. The precise theoretical control over this production channel allows us to set robust
bounds on the vector leptoquark parameter space which are complementary to the other production
channels at colliders. We emphasize the importance of the resonant channel in future searches and
discuss the impact of variations in the model space depending on the flavor structure of the vector
leptoquark couplings.
