论文摘要
由于Lagrangian中存在3和4光子的顶点，因此非交换性QED（NCQED）具有非亚洲性质。因此，NCQED预测了对$γγ\Rightarrowγ$散射的新物理学贡献。我们通过研究具有完整质子的14个TEV LHC的光线过程来检查NCQQEL。我们的结果表明，NC比例最高$λ_{\ MathRM {nc}} = 1.65（1.35）$可以在$ PP \ rightArrow P（γγ）P \ rightArrow P'（γγγ）p'（γγ）p'$ clision p'$ clision中探测到时间跨度（太空空间）NC参数。这些边界比在高能量线性碰撞器处的光线散射中获得的极限要强。
The noncommutative QED (NCQED) has a non-Abelian nature due to the presence of 3- and 4-photon vertices in the lagrangian. Thus, NCQED predicts a new physics contribution to the $γγ\rightarrowγγ$ scattering already at the tree level. We have examined NCQED by studying the light-by-light process at the 14 TeV LHC with intact protons. Our results show that the NC scale up to $Λ_{\mathrm{NC}} = 1.65(1.35)$ TeV can be probed in the $pp\rightarrow p(γγ)p \rightarrow p'(γγ)p'$ collision for the time-space (space-space) NC parameters. These bounds are stronger than the limits that can be obtained in the light-by-light scattering at high energy linear colliders.
