Bounds on neutral and charged Higgs from the LHC

TL;DR

This paper reviews the current experimental bounds and phenomenology of two-Higgs-doublet models, especially focusing on the charged Higgs sector and exploring scenarios like fermiophobic charged Higgses that evade existing bounds.

Contribution

It provides an updated analysis of bounds on neutral and charged Higgs bosons within two-Higgs-doublet models, highlighting the implications of fermiophobic scenarios.

Findings

Fermiophobic charged Higgses evade current experimental bounds.

Alternative decay and production channels are important for detecting such Higgses.

The paper discusses distinctive features of the fermiophobic charged Higgs scenario.

Abstract

After the discovery of a Standard Model-like boson with mass of about 125 GeV the possibility of an enlarged scalar sector arises naturally. Here we present the current status of the phenomenology of the two-Higgs-doublet models with a special focus on the charged Higgs sector. If one considers a fermiophobic charged Higgs (it does not couple to fermions at tree level), all present experimental bounds are evaded trivially, therefore one needs to consider other decay and production channels. In this work we also present some of the interesting features of this specific scenario.
