# Two-Higgs-doublet model of type-II confronted with the LHC run-I and run-II data

## TL;DR

This paper analyzes the parameter space of the type-II two-Higgs-doublet model using LHC data, identifying constraints on Higgs masses and couplings, and exploring viable regions consistent with experimental results.

## Contribution

It provides a comprehensive constraint analysis of the type-II 2HDM parameter space incorporating latest LHC data and theoretical bounds, highlighting allowed and excluded regions.

## Key findings

- Higgs searches strongly constrain CP-odd and heavy CP-even Higgs masses.
- Allowed $m_A$ can be as low as 350 GeV in the SM-like region.
- Certain mass ranges are excluded in the wrong sign Yukawa coupling scenario.

## Abstract

We examine the parameter space of two-Higgs-doublet model of type-II after imposing the relevant theoretical and experimental constraints from the precision electroweak data, $B$-meson decays, the LHC run-I and run-II data. We find that the searches for Higgs via the $\tau\bar{\tau},~WW,~ZZ,\gamma\gamma,~hh,~hZ,~HZ,~AZ$ channels can give strong constraints on the CP-odd Higgs $A$ and heavy CP-even Higgs $H$, and the parameter space excluded by each channel is respectively carved out in detail. The surviving samples are discussed in two different of regions: (i) In the SM-like coupling region of the 125 GeV Higgs, $m_A$ is allowed to be as low as 350 GeV, and $\tan\beta$ is imposed a strong upper limit. $m_H$ is allowed to be as low as 200 GeV for the proper $\tan\beta$, $\sin(\beta-\alpha)$ and $m_A$, but is required to be larger than 300 GeV for $m_A=700$ GeV. (ii) In the wrong sign Yukawa coupling of the 125 GeV, $\tan\beta$ and $\sin(\beta-\alpha)$ can be imposed upper limits by $b\bar{b}\to A/H\to \tau\bar{\tau}$ channel and lower limits by the $A\to hZ$ channel. $m_A$ and $m_H$ are respectively allowed to be as low as 60 GeV and 200 GeV, but 320 GeV $< m_A<$ 500 GeV is excluded for $m_H=$ 700 GeV.
