摘要
In light of the recently obtained LHC Higgs data,we examine the parameter space of the type II twoHiggs-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 of mA 20 GeV,30 mA 120 GeV,240 GeV mA 300 GeV,380 GeV mA 430 GeV,and480 GeV mA 550 GeV.For mA 600 GeV,mH is required to 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.
