Abstract
Searches for heavy Majorana neutrinos in decays in final states containing hadrons plus a pair have been performed using of data collected with the LHCb detector in proton-proton collisions at a center-of-mass energy of 7 TeV. The and final states can arise from the presence of virtual Majorana neutrinos of any mass. Other final states containing , , or 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 decay branching fractions.
