Enhancement of the $H^{\pm }{W}^{\mp }Z$ vertex in the three scalar doublet model

Stefano Moretti, Diana Rojas, Kei Yagyu

We compute one-loop induced trilinear vertices with physical charged Higgs bosons $H^{\pm }$ and ordinary gauge bosons, i.e., $H^{\pm }{W}^{\mp }Z$ and $H^{\pm }{W}^{\mp }\gamma$, in the model with tw…
