An unspecified strong dynamics may give rise to composite vectors sufficiently light that their interactions, among themselves or with the electroweak gauge bosons, be approximately described by an effective Lagrangian invariant under SU(2)(L) x SU(2)(R)/SU(2)(L+R). We study the production at the LHC of two such states by vector boson fusion or by the Drell-Yan process in this general framework and we compare it with the case of gauge vectors from a SU(2)(L) x SU(2)(R) x SU(2)(N) gauge model spontaneously broken to the diagonal SU(2) subgroup by a generic sigma-model. Special attention is payed to the asymptotic behaviour of the different amplitudes in both cases. The expected rates of multi-lepton events from the decay of the composite vectors are also given. A thorough phenomenological analysis and the evaluation of the backgrounds to such signals, aiming at assessing the visibility of composite-vector pairs at the LHC, is instead deferred to future work.
