Özet

The noncommutative QED (NCQED) has a nonAbelian nature due to the presence of 3- and 4-photon vertices in the lagrangian. Thus, NCQED predicts a new physics contribution to the gamma gamma -> gamma gamma scattering already at the tree level. We have examined NCQED by studying the light-bylight process at the 14 TeV LHC with intact protons. Our results show that the NC scale up to Lambda(NC) = 1.64(1.35) TeV can be probed in the pp -> p(gamma gamma)p -> p'(gamma gamma)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.
