We present a detailed analysis of the collider signatures of TeV-scale massive vector bosons motivated by the hints of lepton flavour non-universality observed in B-meson decays. We analyse three representations that necessarily appear together in a large class of ultraviolet-complete models: a colour-singlet (), a colour-triplet (the leptoquark), and a colour octet (). Under general assumptions for the interactions of these exotic states with Standard Model fields, including in particular possible right-handed and flavour off-diagonal couplings for the , we derive a series of stringent bounds on masses and couplings that constrain a wide range of explicit new-physics models.
