Searches for heavy Majorana neutrinos in B - decays in final states containing hadrons plus a μ -μ - pair have been performed using 0.41fb -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 +, Ds+, or D0π + 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.
