QED on the Groenewold Moyal Plane
Abstract
We investigate a version of noncommutative QED where the interaction term, although natural, breaks the spin-statistics connection. We calculate e- + e- -> e- + e- and γ + e- -> γ + e- cross-sections in the tree approximation and explicitly display their dependence on thetaμ . Remarkably the zero of the elastic e- + e- -> e- + e- cross-section at 90-degrees in the center-of-mass system, which is due to Pauli principle, is shifted away as a function of thetaμ and energy.
