Decays of weak vector bosons and t quarks into doubly charged Higgs scalars
Abstract
We evaluate the decays of W^{+} and Z^{0} bosons into χ^{++}, the doubly charged member of the scalar triplet in the GelminiRoncadelli model in which spontaneously broken BL symmetry gives Majorana masses to neutrinos. For M(χ^{++})<28 GeV, the branching fractions exceed 4% for W^{+}>χ^{++}χ^{} and 2% for Z^{0}>χ^{++}χ^{}. Sequential χ^{++}>l^{+}_{1}l^{+}_{2} 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.
