LHCb collaboration, R. Aaij, M. Abdelfatah, A. S. W. Abdelmotteleb et autres
A search for the radiative leptonic decays $B^+\toμ^+ν_μγ$ and $B^+_c\toμ^+ν_μγ$ is performed using proton-proton collision data collected with the LHCb experiment at a center-of-mass energy of $13~{\rm TeV}$, corresponding to an integrated luminosity of $5.4~{\rm fb}^{-1}$. No evidence for an excess of …
