Inhaltsangabe:
- 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.
