Two- and Three Vector Boson Production in e+ e- Collisions within the BESS Model

The BESS model is the Higgsless alternative to the standard model of electroweak interaction with nonlinear realized spontaneous symmetry breaking. Since it is non-renormalizable new couplings (not existing in the SM) are induced at each loop order. On the basis of the one loop induced gauge boson self-couplings we calculated the cross sections for the two and three gauge boson production processes in $e^+e^-$ collisions. Measurements of these cross sections in a planned $e^+e^-$ linear collider at $\sqrt s = 500 GeV$ (NLC) will supply a good empirical test of the gauge boson self interactions and thus should enable to discriminate between SM and its alternatives (BESS).
