Description
We study the implication of the LHC Higgs search results on the Type II Two Higgs-Doublet Models. In particular, we explore the scenarios in which the observed 126 GeV Higgs signal is interpreted as either the light CP-even Higgs h or the heavy CP-even Higgs H. Imposing both
the theoretical and experimental constraints, we analyze the surviving parameter regions in mh, mH, mA, mH±, tanβ and sin(β−α). We further identify the regions that could accommodate a 126 GeV Higgs to be consistent with the observed Higgs signal. We found that in the h-126 case, we are restricted to narrow regions of sin(β−α)∼±1 with tanβ up to 4, or an extended region in sin(β−α) with tanβ<1. The masses for mH, mA and mH±, however, are allowed to vary within a wide range. In the H-126 case, we are restricted to the region of sin(β−α)∼0 while the tanβ region could be extended to 30 or higher. mA and mH± are forced to be nearly degenerate due to the ∆ρ requirement. Imposing the flavor constraints further shrinks the parameter space significantly. We also investigate the correlation between γγ, WW and bb channels. γγ and VV channels are most likely to be highly correlated with γγ:VV ∼ 1 for the normalized cross sections.
