A. Pilaftsis, CP-ODD TADPOLE RENORMALIZATION OF HIGGS SCALAR-PSEUDOSCALAR MIXING - ART. NO. 096010, Physical review. D. Particles and fields, 5809(9), 1998, pp. 6010
We consider an Abelian model with a CP-conserving Higgs potential span
ned by two complex Higgs fields. The CP invariance of the Higgs potent
ial is then broken explicitly beyond the Born approximation by introdu
cing soft-CP-violating Yukawa interactions. Based on the non-renormali
zation theorem, we derive the consistency conditions under which a CP-
odd counterterm exists and, at the same time, renders the one-loop-ind
uced mixing of a CP-even Higgs boson with a CP-odd Higgs scalar ultra-
violet finite. The novel CP-odd tadpole renormalization is uniquely de
termined from the minimization constraints on the Higgs potential. The
main phenomenological consequences of the so-generated CP-violating s
calar-pseudoscalar mixing are briefly discussed. [S0556-2821(98)03821-
