  Prompt photon production is sensitive to the anomalous couplings of gluons to
quarks, because it is mainly produced by quark-gluon scattering. We will
examine the effects of the anomalous chromoelectric and chromomagnetic dipole
moment couplings of quarks on prompt photon production. Using the data
collected by CDF and D0 at the Fermilab Tevatron we put a bound on these
anomalous couplings. We also estimate the sensitivity of various future high
energy collider experiments to these anomalous couplings.
