Degeneracy on a multiHiggs CP non invariant sector.

Speaker

Dr Melina Gomez Bock (Universidad de las Americas Puebla)

Description

The Higgs sector with more than one Higgs doublet may have de\-ge\-ne\-ra\-cy in its physical states. Considering also $CP$ symmetry is not conserved in the Higgs sector, then the neutral Higgs states would not have a defined $CP$ charge,{\it i.e.} there is a mixing within scalar and pseudoscalar components of the Higgs doublets. This situation will occur for the cMSSM, {\it i.e.} with complex soft couplings, and will be manifest through one-loop corrections. This possibility has consequences on the phenomenology and in the type of expected signatures for the nearly and exact Higgs de\-ge\-ne\-ra\-cy, as for example the line-shape will present very different behaviour than expected for the fermion scattering amplitude via $non-CP$ defined Higgs, $\sigma(f \bar{f} \to H_{i}^{non CP} \to f'\bar{f'})$.
