This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data taken with the Collider Detector at Fermilab (CDF) during the 1992--1993 run of the Tevatron are used to measure the distribution of the center-of-mass angle between isolated prompt photons and the beam direction. The shape of the angular distribution for photon-jet events is found to differ from the predictions of NLO QCD.
