Neutral Trilinear Gauge Boson Couplings in Little Higgs Models

Abstract

We compute the one loop new physics effects to the CP even triple neutral gauge boson vertices ${\gamma }^{\star }\gamma Z$, ${\gamma }^{\star }ZZ$, $Z^{\star }Z\gamma$ and $Z^{\star }ZZ$ in the context of Little Higgs models. In addition, we re-examine the MSSM contribution at the chosen point of SPS1a' and compare with the SM and Little Higgs models.
