Query: Direct Photon Results from CDF   Direct (prompt) photon production is a field of very high interest in hadron
colliders. It provides probes to search for new phenomena and to test QCD
predictions. In this article, two recent cross-section results for direct
photon production using the full CDF Run II data set are presented: diphoton
production and photon production in association with a heavy quark.
