First observation of the radiative decay $\Lambda_{b}^{0} \to \Lambda \gamma$ / LHCb Collaboration
The radiative decay $\Lambda_{b}^{0} \to \Lambda \gamma$ is observed for the first time using a data sample of proton-proton collisions corresponding to an integrated luminosity of $1.7\,fb^{-1}$ collected by the LHCb experiment at a center-of-mass energy of $13\,TeV$. [...]
