High Energy Physics - Phenomenology 2015-06-15 v2

Abstract

We analyze the Type-II two Higgs doublets model in light of the newly discovered Higgs-like particle with mass 125 GeV. The observed 125 GeV particle is identified with the light CP-even Higgs boson in the two Higgs doublets model. We study the parameter space of the model consistent with the Higgs data, branching ratio of BˉXsγ\bar{B}\to X_s\gamma as well as precision electroweak measurements. We also incorporate theoretical constraints--- perturbativity of the couplings and vacuum stability, in our study. We find that only a small parameter space of the model remains viable. The phenomenology of the heavy Higgs bosons in the surviving parameter space is studied.

Revise the CP odd scalar branching ratios. Main conclusion remains unchanged
