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 , , and correspond to the most preferred scenario are found to be about 6 TeV, 3.6 TeV, −6.9 TeV and 36.8 respectively.

约束MSSM的信息理论探索
我们根据在大型强子对撞机上希格斯玻色子的观测,讨论信息理论作为研究约束最小超对称标准模型(CMSSM)的工具。希格斯玻色子利用其各种检测模式的熵被构造为信息的量度,并且在包括来自LEP数据,B物理,电弱精确观测值的各种实验约束之后,已被用于探索广泛的CMSSM参数空间。和暗物质的遗迹密度。根据我们的研究,虽然最轻的中性素质量最好在1.92 TeV左右,但葡糖酐质量估计在7.44 TeV左右。CMSSM参数的值, , 和 对应于最优选情形的值分别被发现为约6 TeV,3.6 TeV,-6.9 TeV和36.8。
