论文摘要
我们调查可逆$θ$ - 外观seiberg-witten（SW）基于非交通量（NC）量子电动力学的散射幅度，并明确显示了所有树级NCQED NCQED $ 2 \ to2 $ Process的SW地图不变性，包括Möller，Babbha，Babhha，compton，compton，compton，配对，配对，配对，fight，fight and fromight和 - $（γγ\toγγ）$散射。我们将NCQED结果应用于$γγ\toγγ$和$γγ\ to \ ell^+\ ell^ - $独家过程，该过程响应于超固定铅$^{208} $ pb ion-ion-ion-ion碰撞，最近由Atlas在LHC的Atlas Colarecoration衡量。我们证明$γγ\toγγ$是探测NC尺度$λ_{\ rm nc} $的更合适的通道，而两者都比其他探针效率低。
We investigate Scattering amplitudes of the reversible $θ$-exact Seiberg-Witten (SW) map based noncommutative (NC) quantum electrodynamics, and show explicitly the SW map invariance for all tree-level NCQED $2\to2$ proceses, including Möller, Bhabha, Compton, pair annihilation, pair production and light-by-light $(γγ\toγγ)$ scatterings. We apply our NCQED results to the $γγ\toγγ$ and $γγ\to\ell^+\ell^-$ exclusive processes, convoluted to the ultraperipheral lead $^{208}$Pb ion-ion collisions, recently measured by the ATLAS collaboration at LHC. We demonstrate that $γγ\toγγ$ is the more appropriate channel to probe NC scale $Λ_{\rm NC}$ while both are less efficient than some other probes.
