Improved limit on the branching fraction of the rare decay [Formula omitted]

A search for the decay [Formula omitted] is performed, based on a data sample of proton-proton collisions corresponding to an integrated luminosity of [Formula omitted], collected by the LHCb experiment at centre-of-mass energies of 7 and 8 [Formula omitted]. The observed yield is consistent with th...

Description
Summary:	A search for the decay [Formula omitted] is performed, based on a data sample of proton-proton collisions corresponding to an integrated luminosity of [Formula omitted], collected by the LHCb experiment at centre-of-mass energies of 7 and 8 [Formula omitted]. The observed yield is consistent with the background-only hypothesis, yielding a limit on the branching fraction of [Formula omitted] at [Formula omitted] confidence level. This result improves the previous upper limit on the branching fraction by an order of magnitude.
