Angular distribution of prompt photon
Experiment: CDF (Tevatron Run 1)

Beams: p- p+
Beam energies: (900.0, 900.0) GeV
Run details:
• All prompt photon production processes in $p \bar{p}$ at 1800 GeV. Hadronisation should be switched off, because non-prompt photon production has been corrected for.

Data taken with the Collider Detector at Fermilab (CDF) during the 1988-1989 run of the Tevatron are used to measure the distribution of the center-of-mass (rest frame of the initial state partons) angle between isolated prompt photons and the beam direction. WARNING --- Implemented is the simplified c.m. definition given in the paper. The rise of the data and the MC predictions presented in the latter could not be reproduced.
