Testing Non commutative QED gamma-gamma-gamma and gamma-gamma-gamma-gamma Couplings at LHC

Abstract

In this work, we investigate the sensitivity of the process p + p --> q + q --> j + j + gamma + gamma at LHC for the photonic 3- and 4- point functions that appear in non commutative QED. We show that this process serves to study the behavior of the space-space as well as of the space-time non commutativity. We also show that this process can probe the non commutative scale in the range of few TeV.
