Searches for heavy Majorana neutrinos in B- decays in final states containing
hadrons plus a \mu- \mu- pair have been performed using 0.41/fb of data
collected with the LHCb detector in proton-proton collisions at a
center-of-mass energy of 7 TeV. The D+ \mu- \mu- and D*+ \mu- \mu- final states
can arise from the presence of virtual Majorana neutrinos of any mass. Other
final states containing \pi+, Ds+, or D0\pi+ 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.
