Constraints on Anomalous Gauge Boson Couplings From $b \to sγ$
arXiv:hep-ph/9304263 · doi:10.1016/0370-2693(93)91643-2
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 $Wγ$ production to highly constrain the anomalous trilinear gauge couplings of the $W$. The theoretical analysis of the $b \to sγ$ process employs, next-to-leading order operator coefficient evolution as well as QCD bremsstrahlung and appropriate phase space corrections.
