Abstract: (APS)
We evaluate the decays of W+ and Z0 bosons into χ++, the doubly charged member of the scalar triplet in the Gelmini-Roncadelli model in which spontaneously broken B−L symmetry gives Majorana masses to neutrinos. For M(χ++)<28 GeV, the branching fractions exceed 4% for W+→χ++χ− and 2% for Z0→χ++χ−−. Sequential χ++→l1+l2+ leptonic decays could be substantially higher than previously recognized and could be dominant. Decay distributions for leptons of this origin are calculated for p¯p colliders. We also evaluate t→bχ++χ− decay.- POSTULATED PARTICLE: W+
