Abstract

The possibility of observing CP-violating effects in the “Higgs bosons–SM particles” interactions in the type-II 2HDM with an explicit and spontaneous CP-violation is discussed. It is shown that in the Higgs alignment limit, unambiguous predictions can be deduced in the general form. According to the numerical estimations performed according to the MSSM CPX-scenario, the observation of CP-violating signals in the Higgs sector is most likely at the characteristic mass scale of superpartners MSUSY ~ 2 TeV and \(\tan \beta \) = 5.
