Abstract
We discuss information theory as a tool to investigate constrained minimal supersymmetric Standard Model (CMSSM) in the light of observation of Higgs boson at the Large Hadron Collider. The entropy of the Higgs boson using its various detection modes has been constructed as a measure of the information and has been utilized to explore a wide range of CMSSM parameter space after including various experimental constraints from the LEP data, B-physics, electroweak precision observables and relic density of dark matter. According to our study while the lightest neutralino is preferred to have a mass around 1.92 TeV, the gluino mass is estimated to be around 7.44 TeV. The values of CMSSM parameters m0, m1/2, A0 and tanβ correspond to the most preferred scenario are found to be about 6 TeV, 3.6 TeV, −6.9 TeV and 36.8 respectively.
Highlights
The recent discovery of Higgs boson and the subsequent measurement of its mass through various detection modes at the Large Hadron Collider (LHC) [1] have been found to be consistent with the Standard Model (SM) predictions
It opens up the scope of looking for counterparts of the SM particles known as the superparticles which are differing by spin-1/2 in the minimal extension of SM, known as the minimal supersymmetric Standard Model (MSSM) [9,10,11,12,13,14]
The Higgs sector in MSSM is enhanced by one CP-even heavier neutral Higgs boson (H), a CP-odd neutral Higgs boson (A0) and charged Higgs boson (H±)
Summary
The recent discovery of Higgs boson and the subsequent measurement of its mass through various detection modes at the Large Hadron Collider (LHC) [1] have been found to be consistent with the Standard Model (SM) predictions. Among several interesting candidate theories, supersymmetry (SUSY) [3,4,5,6,7,8,9,10] is still sought to be one of the most preferred choices as it is capable of solving most of the aforementioned problems It opens up the scope of looking for counterparts of the SM particles known as the superparticles which are differing by spin-1/2 in the minimal extension of SM, known as the minimal supersymmetric Standard Model (MSSM) [9,10,11,12,13,14]. According to the finding of this article the maximum entropy technique is capable of predicting the Higgs mass very close to its measured value at the LHC. The maximum entropy principle has been successfully applied in the context of studying new decay modes of Higgs boson at the LHC in Ref.
