Abstract: Searches for heavy Majorana neutrinos in B − decays in final states containing hadrons plus a μ − μ − pair have been performed using 0.41     fb − 1 of data collected with the LHCb detector in proton-proton collisions at a center-of-mass energy of 7 TeV. The D + μ − μ − and D * + μ − μ − final states can arise from the presence of virtual Majorana neutrinos of any mass. Other final states containing π + , D + s , or D 0 π + can be mediated by an on-shell Majorana neutrino. No signals are found and upper limits are set on Majorana neutrino production as a function of mass, and also on the B − decay branching fractions.
