  Extensions of the Standard Model of elementary particle physics to
noncommutative geometries have been proposed as a low energy limit of string
models. Independent of this motivation, one may consider such a model as an
effective field theory with higher-dimensional operators containing an
antisymmetric rank-two background field. We study the signals of such a
Noncommutative Standard Model (NCSM) and analyze the discovery potential of a
future photon collider, considering angular distributions in fermion pair
production.
