Compton scattering in noncommutative space-time at the Next Linear Collider

We study Compton scattering in the noncommutative (NC) counterpart of QED. Interactions in NC QED have momentum dependent phase factors and the gauge fields have Yang-Mills type couplings; this modifies the cross sections and they are different from the commuting standard model. Collider signals of noncommutative space-time are studied at the Next Linear Collider (NLC) operating in the $e\gamma$ mode. Results for different polarized cases are presented and it is shown that the Compton process can probe the noncommutative scale in the range of 1–2.5 TeV for typical proposed NLC energies.
