约束MSSM的信息论探讨

An Information Theoretic Exploration of Constrained MSSM

Surabhi Gupta, Sudhir Kumar Gupta

摘要:

本文以大型强子对撞机上观测到的希格斯玻色子为背景,讨论了信息论作为研究约束最小超对称标准模型(CMSSM)的工具。希格斯玻色子的熵,使用其各种检测模式已被构造为一个衡量的信息,并已被用来探索广泛的CMSSM参数空间后,包括各种实验约束的LEP数据,B-物理,电弱精密观测和遗迹密度的暗物质。根据我们的研究,最轻的中性伴子的质量最好在1.92 TeV左右,而胶子的质量估计在7.44 TeV左右。发现对应于最优选方案的CMSSM参数$m_0$、$m_{1/2}$、$A_0$和$\tanβ$的值分别为约6 TeV、3.6 TeV、$-$ 6.9 TeV和36.8。

英文摘要:

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 $m_0$, $m_{1/2}$, $A_0$ 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.
