摘要:

在最小超对称标准模型下,研究了在欧洲核子研究中心(CERN)大型强子-电子对撞机上产生的轻CP偶中性希格斯玻色子与电子和喷流的关系.我们研究了可能的超对称效应对这个过程的影响,并将我们的标准模型数值结果与以前的工作进行了比较。给出了最小超对称标准模型中末态电子、轻中性希格斯玻色子玻色子和喷注的首阶和次首阶QCD修正总截面以及横动量分布.我们的结果表明,QCD次首阶修正明显降低了首阶截面的标度依赖性。在我们选取的参数空间中,当因子化/重整化标度$μ$从$0.2 m_Z$增加到$3.8 m_Z$时,QCD对大型强子-电子对撞机总截面的修正K因子从0.893变化到1.048。

英文摘要:

We study the light CP-even neutral Higgs boson production in association with an electron and a jet at the possible CERN large hadron-electron collider within the minimal supersymmetric standard model. We investigate the possible supersymmetric effects on this process and compare our standard model numerical results with those in previous work. We present the leading-order and QCD next-to-leading-order corrected total cross sections and the distributions of the transverse momenta of the final electron, the light neutral Higgs boson, and jet in the minimal supersymmetric standard model. Our results show that the scale dependence of the leading-order cross section is obviously reduced by the QCD next-to-leading-order corrections. The K factor of the QCD correction to the total cross section at the large hadron-electron collider varies from 0.893 to 1.048 when the factorization/renormalization scale $μ$ goes up from $0.2 m_Z$ to $3.8 m_Z$ in our chosen parameter space.
