abstract

We point out that the rare decay mode $W^{\pm} \rightarrow \gamma + D^{\pm}_{s} $ could be spectacularly enhanced, with a branching ratio around $10^{-6} $ which is three order of magnitude larger than previous predictions. Its observation will determine the W boson mass with great accuracy, providing additional high precision tests of the standard model, as well as reveal eventual deviation from the trilinear non-abelian gauge coupling.

Rare $W \to B_c + \gamma$ decay up to the NNLO and NLL accuracy in QCD
hep-ph 2025-02 conditional novelty 6.0 of 10

The rare decay W to Bc plus photon gets NNLO QCD corrections that reduce the width by 31 percent, giving a branching fraction of 1.522 times 10 to the minus 10 after NLL resummation.
