Abstract.

In this work, we investigate the sensitivity of the process \(p + p \to q + q \to j + j + \gamma + \gamma \) 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 \(\Lambda\) in the range of a few TeV.
