Revisiting wrong sign Yukawa coupling of type II two-Higgs-doublet model in light of recent LHC data

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 m_H 600 GeV, the allowed samples are mainly distributed across several corners and narrow bands of m_A 20 GeV, 30 m_A 120 GeV, 240 GeV m_A 300 GeV, 380 GeV m_A 430 GeV, and480 GeV m_A 550 GeV. For m_A 600 GeV, m_H 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.
