Abstract

Composite Higgs models generically predict the existence of heavy spin-1 resonances with the same quantum numbers as electroweak gauge bosons. The effective lagrangian description of these resonances is presented, pointing out the origin of their interactions with SM matter fields and the resulting LHC phenomenology. Search strategies for spin-1 resonances are discussed, mentioning possible advantages offered by boosted decay products. The impact of interactions between spin-1 resonances and fermion resonances, crucial for the proper interpretation of LHC searches, is pointed out.
