Abstract
Prompt photon production has been known to be a sensitive probe to the gluon luminosity inside a hadron because it is mainly produced by quark-gluon scattering. For the same reason prompt photon production should also be sensitive to the anomalous couplings of gluons to quarks. We will examine the effects of two specific anomalous couplings -- chromoelectric and chromomagnetic dipole moments of quarks -- on the prompt photon production. Using the data collected by CDF and D0 at the Tevatron we put a bound on the these anomalous couplings.
