非对易标准模型中LC的中性希格斯玻色子对产生

Neutral Higgs boson pair production at the LC in the Noncommutative Standard Model

Prasanta Kumar Das, Abhishodh Prakash, Anupam Mitra

摘要:

我们研究了在非对易(NC)扩展的标准模型中通过$e^+e^-$碰撞产生的希格斯玻色子对,利用Seiberg-Witten映射到非对易参数$Θ_{μν}$的一阶.这个过程在背景时空可交换的标准模型中是不允许的。我们发现,在未来的直线对撞机(LC)上,中重质量的希格斯玻色子对产生的截面对于处于$0.5 - 1.0$ TeV的NC尺度的$Λ$是相当重要的.最后,利用直接实验方法(LEP II,Tevatron和整体电弱拟合)得到了Higgs质量的NC尺度上的束缚为665 GeV $\le Λ\le 998$ GeV.

英文摘要:

We study the Higgs boson pair production through $e^+e^-$ collision in the noncommutative(NC) extension of the standard model using the Seiberg-Witten maps of this to the first order of the noncommutative parameter $Θ_{μν}$. This process is forbidden in the standard model with background space-time being commutative. We find that the cross section of the pair production of Higgs boson (of intermediate and heavy mass) at the future Linear Collider(LC) can be quite significant for the NC scale $Λ$ lying in the range $0.5 - 1.0$ TeV. Finally, using the direct experimental(LEP II, Tevatron and global electro-weak fit) bound on Higgs mass, we obtain bounds on the NC scale as 665 GeV $\le Λ\le 998$ GeV.
