A search for the rare decaysandis performed using proton–proton collision data collected with the LHCb detector. The data sample corresponds to an integrated luminosity ofcollected in 2011 and 2012. Theleptons are reconstructed through the decay. Assuming no contribution fromdecays, an upper limit is set on the branching fractionat the 95% confidence level. If instead no contribution fromdecays is assumed, the limit isat the 95% confidence level. These results correspond to the first direct limit onand the world’s best limit on.
