CERN LHC能量下强子碰撞中Υ光生的QCD研究

QCD of Υ photo-production in hadronic collision at CERN LHC energies

在广义QCD矢量介子为主理论的基础上,用有QCD特征的程函模型研究质子-质子和质子-核子碰撞过程中Υ光生的总截面滓.计算结果与实验数据基本符合,表明QCD机制能够很好解释在质子-质子和质子-核子碰撞中Υ光生过程,为研究超标准模型的新物理提供新思路.

We propose a QCD inspired eikonal model to study the total section σ of Υ photo-production for protonproton and proton-nucleus collision at LHC energies. The theoretical results are generally consistent with the experimental data. It shows that QCD mechanism is good description of exclusive Υ photo-production for proton-proton and proton-nucleus collision, and can provide new ideas to search for new physics beyond the Standard Model.
