Evidence for the rare decay $\Sigma^+ \to p \mu^+ \mu^-$
A search for the rare decay $\Sigma^+ \to p \mu^+ \mu^-$ is performed using $pp$ collision data recorded by the LHCb experiment at centre-of-mass energies $\sqrt{s} = 7$ and $8 TeV$, corresponding to an integrated luminosity of $3 ~ \text {fb}^{-1}$. An excess of events is observed with respect to...
