Neutral Higgs production on LHC in the two-Higgs-doublet model with spontaneous $CP$ violation

TL;DR

This paper investigates how the production and decay of neutral Higgs bosons at the LHC differ in a two-Higgs-doublet model with spontaneous CP violation, highlighting potential signals of new physics beyond the standard model.

Contribution

It provides a detailed analysis of neutral Higgs production in a two-Higgs-doublet model with spontaneous CP violation, emphasizing deviations from standard model predictions.

Findings

Neutral Higgs production cross section can be significantly different from the standard model.

Decay patterns of neutral Higgs bosons show notable differences from standard model expectations.

Spontaneous CP violation introduces new sources of CP violation affecting Higgs phenomenology.

Abstract

Spontaneous CP violation motivates the introduction of two Higgs doublets in the electroweak theory, such a simple extension of the standard model has five physical Higgs bosons and rich CP-violating sources. Exploration on more than one Higgs boson is a direct evidence for new physics beyond the standard model. The neutral Higgs production at LHC is investigated in such a general two Higgs doublet model with spontaneous CP violation, it is shown that the production cross section and decays of the neutral Higgs boson can significantly be different from the predictions from the standard model.
