Abstract
We investigate a version of noncommutative QED where the interaction term, although natural, breaks the spin-statistics connection. We calculate and cross-sections in the tree approximation and explicitly display their dependence on theta^{\mu \nu}. Remarkably the zero of the elastic cross-section at 90-degrees in the center-of-mass system, which is due to Pauli principle, is shifted away as a function of theta^{\mu \nu} and energy.
