abstract="A search for the rare leptonic decay B +. $\mu$+ $\mu$- $\mu$+.mu is performed using proton- proton collision data corresponding to an integrated luminosity of 4.7 fb -- 1 collected by the LHCb experiment. The search is carried out in the region where the lowest of the two $\mu$+ $\mu$- mass combinations is below 980 MeV/ c2. The data are consistent with the background- only hypothesis and an upper limit of 1.6x10 -- 8 at 95{\%} confidence level is set on the branching fraction in the stated kinematic region.",
