Evidence for the decay

A bstract Evidence is presented for the decay using proton-proton collision data, corresponding to an integrated luminosity of 3 fb −1 , collected with the LHCb detector. A signal yield of 32 ± 8 decays is found with a significance of 4.5 standard deviations. The ratio of the branching fraction of t...

Beschreibung
Zusammenfassung:	A bstract Evidence is presented for the decay using proton-proton collision data, corresponding to an integrated luminosity of 3 fb −1 , collected with the LHCb detector. A signal yield of 32 ± 8 decays is found with a significance of 4.5 standard deviations. The ratio of the branching fraction of the decay to that of the decay is measured to be where the first uncertainty is statistical and the second is systematic.
