Description
In the type II seesaw mechanism introducing a hypercharged triplet boson, the neutral components can exhibit a novel phenomenon of the triplet-antitriplet oscillation resulting in same-sign tetra-lepton final states at the LHC. After discussing the production cross-sections in the parameter space of the mass splitting among triplet components and the triplet vacuum expectation value, we provide a LHC analysis of the same-sign tetra-lepton signals for the benchmark point chosen to maximize the event number.
