Abstract

We study lepton number violating decays of charged K, D, Ds, B, and Bc mesons of the form M+→M′-ℓ+ℓ, induced by the existence of Majorana neutrinos. These processes provide information complementary to neutrinoless double nuclear beta decays, and are sensitive to neutrino masses and lepton mixing. We explore neutrino mass ranges mN from below 1 eV to several hundred GeV. We find that in many cases the branching ratios are prohibitively small, however in the intermediate range mπ<mN<mBc, in specific channels and for specific neutrino masses, the branching ratios can be at the reach of high luminosity experiments like those at the LHC-b and future super flavor factories, and can provide bounds on the lepton mixing parameters.
