We investigate trilepton final states to probe top anomalous couplings at the
Large Hadron Collider. We focus on events originating from the associated
production of a single top quark with a Z-boson, a channel sensitive to several
flavor-changing neutral interactions of top and up/charm quarks. In particular,
we explore a way to access simultaneously their anomalous couplings to Z-bosons
and gluons and derive the discovery potential of trilepton final states to such
interactions with 20 fb-1 of 8 TeV collisions. We show that effective coupling
strengths of O(0.1-1) TeV-1 can be reached. Equivalently, branching fractions
of top quarks into lighter quarks and gluons or Z-bosons can be constrained to
be below O(0.1-1)%.
