  Heavy vector-boson hunting is one of the major analyses undertaken by the
experiments carried out at the LHC. I will explore two scenarios which have not
been investigated yet by the experimental collaborations. The first scenario
consists in searching for Z' bosons, predicted by U(1)' GUT-inspired models, by
studying its supersymmetric decays, leading to resonant final states with
charged leptons and missing energy. Afterwards, I shall discuss the 331 model
and the production of doubly-charged vector bileptons, yielding events with two
same-sign lepton pairs at the LHC.
