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+, Ds+, or D0π+ can be mediated by an on-shell Majorana neutrino.

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+, 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.
