Probing loop effects in wrong-sign Yukawa region of 2HDM

Abstract

In the framework of 2HDM, we explore the wrong-sign Yukawa region with direct and indirect searches up to one-loop level. The direct searches include the latest $H/A\to f\bar{f},VV,Vh,hh$ reports at current LHC, and the study of indirect Higgs precision measurements works with current LHC, future HL-LHC and CEPC. At tree level of Type-II 2HDM, for degenerate heavy Higgs mass $m_A=m_H=m_{H^{\pm }}<800$ GeV, the wrong-sign Yukawa regions are excluded largely except for the tiny allowed region around $\cos (\beta -\alpha )\in (0.2,0.3)$ under the combined constraints. The excluded region is also nearly independent of parameter $m_{12}$ or $\lambda v^2=m_A^2-m_{12}^2/(\sin \beta \cos \beta )$. The situation changes a lot after including loop corrections to the indirect searches, for example $m_A=800$ GeV, the region with $\lambda v^2<0$ will be stronger constrained to be totally excluded. Whilst $\lambda v^2>0$ would get larger survived wrong-sign region, such as $\cos (\beta -\alpha )\in (0,0.3)$ for $\sqrt{\lambda v^2}=400$ GeV, under combined restrictions.
