AbstractWe investigate the collider phenomenology of the scalar triplet particles in the Type-II seesaw model at a 100 TeV pp collider. Depending on triplet vacuum expectation value v (Delta), the dominant discovery channels could be H (++) H (--) and H (+/-+/-) H (a"). We find the H (+/-+/-) H (a") -> W (+/-) W (+/-) hW (a") /a"" (+/-) a"" (+/-) hW (a") channels are promising for both model discovery at relatively large v (Delta) and determination of the Higgs portal couplings lambda (4) and lambda (5). We also find that these two channels are complementary to indirect determination of lambda (4) from future precise measurements on h -> gamma gamma decay rate. Together with pair production of the doubly-charged Higgs subsequently decaying into same-sign di-leptons, the H (+/-+/-) H (a") channels have the potential to cover a significant portion of the parameter space of the Type-II seesaw complex scalar triplet model.
