One-loop pseudoscalar mass in a 2HDM with a Z 3 symmetry
Abstract A two-Higgs doublet model with a discrete Z 3 symmetry acquires, in its scalar and gauge sectors, an accidental continuous U(1) symmetry. One therefore finds, after spontaneous symmetry breaking of those symmetries, that a massless pseudoscalar arises, as expected by Goldstone’s theorem. In...
