Abstract

Information theory turns out to be an interesting tool for studying the consequences of Higgs observations to various new physics candidate theories by means of the information measure as the entropy of Higgs-Boson through its various detection modes at the Large Hadron Collider. The present article investigates the parameter space of a supersymmetric scenario where sfermions and one of the Higgs superfields are decoupled, while the gauginos, Higgsinos, and the remaining Higgs doublet are still allowed to be lighter. Our analysis reveals that this is quite a viable choice in the light of LHC discovery of a Higgs which resembles the SM Higgs-Boson and nothing else so far. While the supersymmetry breaking scale MSM_S could be as high as 101110^{11} GeV or so, the most preferred values of the MSM_{S} and tanβ\tan\beta are found to be around 3.6×107\times10^7 GeV and 4141 respectively, which is also consistent with the relic abundance of the neutralino dark matter. The corresponding value of neutralino (mχ~10 m_{\tilde\chi^{0}_{1}}) LSP is estimated to be around 1.01 TeV. The preferred values of other parameters, namely, the Higgsino mass (μ\mu) and gaugino mass parameters (M1M_1 and M2M_2) are found to be about 1.05 TeV, 1.74 TeV, and 2.57 TeV, respectively.
