No strong CP violation up to the one-loop level in a two-Higgs-doublet model
No strong CP violation up to the one-loop level in a two-Higgs-doublet model
We put forward a two-Higgs-doublet model, furnished with a $$\mathbb {Z}_3$$ symmetry, wherein CP is conserved in the dimension-four terms of the Lagrangian and is softly broken in the scalar potential. The new particles of our model are one neutral scalar H, one neutral pseudoscalar A, and two charged scalars …
