摘要:

本文研究了希格斯玻色子在$e^+e^-\to Z H$过程中的角分布和在最小非对易标准模型(mNCSM)框架下的总截面对设定非对易特征标度($Λ$)下限的敏感性.与标准模型的情况相反,在这个过程中,希格斯玻色子倾向于在横向平面内各向异性地发射。基于这一事实,使用轮廓似然比来设置关于$Λ$的下限。下限作为积分亮度的函数。我们表明,在质心能量为1.5 TeV和500 fb的$^{-1}$的数据,非对易的特征能量标度$Λ$可以排除高达1.2 TeV。

英文摘要:

We examine the sensitivity of the angular distribution of the Higgs boson in the process of $e^+e^-\to Z H$ and the total cross section in the minimal noncommutative standard model (mNCSM) framework to set lower limit on the noncommutative charactristic scale ($Λ$). Contrary to the standard model case, in this process the Higgs boson tends to be emitted anisotropically in the transverse plane. Based on this fact, the profile likelihood ratio is used to set lower limit on $Λ$. The lower limit is presented as a function of the integrated luminosity. We show that at the center-of-mass energy of 1.5 TeV and with 500 fb$^{-1}$ of data, the noncommutative characteristic energy scale $Λ$ can be excluded up to 1.2 TeV.
