A search is performed for the lepton number violating decay B+ h- mu+ mu+, where h- represents a K- or a pi-, using an integrated luminosity of 36pb(-1) of data collected with the LHCb detector. The decay is forbidden in the standard model but allowed in models with a Majorana neutrino. No signal is observed in either channel and limits of B(B+ K- mu+ mu+) < 5.4*10(-8) and B(B+ pi- mu+ mu+) < 5.8*10(-8) are set at the 95% confidence level. These improve the previous best limits by factors of 40 and 30, respectively.

Abstract
A search is performed for the lepton number violating decay B+ h- mu+ mu+, where h- represents a K- or a pi-, using an integrated luminosity of 36pb(-1) of data collected with the LHCb detector. The decay is forbidden in the standard model but allowed in models with a Majorana neutrino. No signal is observed in either channel and limits of B(B+ K- mu+ mu+) < 5.4*10(-8) and B(B+ pi- mu+ mu+) < 5.8*10(-8) are set at the 95% confidence level. These improve the previous best limits by factors of 40 and 30, respectively.
