LHCb: First observation of $B^+ \to \pi^+ \mu^+ \mu -$ with LHCb
A search for the decay $B^+ \to \pi^+ \mu^+ \mu^-$ is presented using 1.0 fb$^{-1}$ of pp collision data integrated luminosity collected with the LHCb experiment at the Large Hadron Collider during 2011. This decay is observed for the first time with 5.2 $\sigma$ significance, at a branching fracti...
