F. Abe et al., PRECISION-MEASUREMENT OF THE PROMPT PHOTON CROSS-SECTION IN P(P)OVER-BAR COLLISIONS AT ROOT-S=1.8 TEV, Physical review letters, 73(20), 1994, pp. 2662-2666
A prompt photon cross section measurement from the Collider Detector a
t Fermilab experiment is presented. Detector and trigger upgrades, as
well as 6 times the integrated luminosity compared with our previous p
ublication, have contributed to a much more precise measurement and ex
tended P-T range. As before, QCD calculations agree qualitatively with
the measured cross section, but the data has a steeper slope than the
calculations.
