dc.description.abstractIn 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→ff¯,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 mA=mH=mH±<800 GeV, the wrong-sign Yukawa regions are excluded largely except for the tiny allowed region around cos(β−α) ∈ (0.2,0.3) under the combined Higgs constraints. The excluded region is also nearly independent of parameter m12 or λv2=m2A−m212/ (sinβcosβ). The situation changes a lot after including loop corrections to the indirect searches, for example mA=1500~GeV, the region with λv2<0 will be stronger constrained to be totally excluded. Whilst parameter space with λv2>0 would get larger survived wrong-sign region for mA=800 ~GeV compared to it at tree level. We also conclude Higgs direct searches works better on constraining λv2≈0 GeV range than theoretical constraints. We also find that the loop-level wrong-sign Yukawa limit only occurs at mass decoupling scale.-
