摘要

In light of the recently obtained LHC Higgs data,we examine the parameter space of the type Ⅱ two-Higgs-doublet model,in which the 125 GeV Higgs bosons exhibit wrong sign Yukawa couplings.Combining the relevant theoretical and experimental limits,we find that the LHC Higgs data exclude most of the parameter space of the wrong sign Yukawa coupling.For mH =600 GeV,the allowed samples are mainly distributed across several corners and narrow bands ofmA ＜ 20 GeV,30 ＜ mA ＜ 120 GeV,240 GeV ＜ mA ＜ 300 GeV,380 GeV ＜ mA ＜ 430 GeV,and 480 GeV ＜ mA ＜ 550 GeV.For mA =600 GeV,mH is requiredto be lower than 470 GeV.The light pseudo-scalar with a mass of 20 GeV is still permitted in the case of the wrong sign Yukawa coupling of 125 GeV Higgs bosons.
