Possible huge enhancement in the radiative decay of the weal W boson into the charmed $D_{s} $ meson by Keum, Y. Y.; Pham, X. Y. is a scholarly article available to read on EtoBox.

What is Possible huge enhancement in the radiative decay of the weal W boson into the charmed $D_{s} $ meson about?

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.
