Constraints on the anomalous $WWγ$ couplings from $b\rightarrow sγ$

Abstract

We study contributions to $b \rightarrow s γ$ from anomalous $WWγ$ interactions. Although these anomalous interactions are not renormalizable, the contributions are cut-off independent. Using recent results from the CLEO collaboration on inclusive radiative B decays, we obtain bounds for the anomalous CP conserving and CP violating couplings. The constraints on the CP conserving couplings are comparable with or better than constraints from other experiments.
