Search for Majorana Neutrinos in B[superscript −] → π[superscript +]μ[superscript −]μ[superscript −] Decays
A search for heavy Majorana neutrinos produced in the B[superscript −] → π[superscript +]μ[superscript −]μ[superscript −] decay mode is performed using 3 fb[superscript −1] of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV at the LH...

| description | A search for heavy Majorana neutrinos produced in the B[superscript −] → π[superscript +]μ[superscript −]μ[superscript −] decay mode is performed using 3 fb[superscript −1] of integrated luminosity collected with the LHCb detector in pp collisions at center-of-mass energies of 7 and 8 TeV at the LHC. Neutrinos with masses in the range 250 to 5000 MeV and lifetimes from zero to 1000 ps are probed. In the absence of a signal, upper limits are set on the branching fraction B(B[superscript −] → π[superscript +]μ[superscript −]μ[superscript −]) as functions of neutrino mass and lifetime. These limits are on the order of 10[superscript −9] for short neutrino lifetimes of 1 ps or less. Limits are also set on the coupling between the muon and a possible fourth-generation neutrino. |
