CP violating form factors for three gauge boson vertices in the two-Higgs doublet and left-right symmetric models

Abstract In this paper we calculate the one loop contributions to the CP violating three gauge boson couplings in two-Higgs doublet and left-right symmetric models. In the two-Higgs doublet model only a P conserving and CP violating coupling is generated, and it can be as large as 10 −3 . In the left-right symmetric model both P conserving and violating couplings are generated. Due to constraints on the W inL− W inR mixing, these couplings are small.
