摘要：

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 DO at the Fermilab Tevatron we put a bound an these anomalous couplings. We also estimate the sensitivity of various future high energy collider experiments to these anomalous couplings.
