Constraints on Anomalous Gauge Boson Couplings From $b\to s\gamma$

Abstract

The recent results of the CLEO Collaboration on both inclusive and exclusive radiative $B$ decays are combined with those of the UA2 Collaboration on $W\gamma$ production to highly constrain the anomalous trilinear gauge couplings of the $W$. The theoretical analysis of the $b\to s\gamma$ process employs, next-to-leading order operator coefficient evolution as well as QCD bremsstrahlung and appropriate phase space corrections.
