Precision measurement of the prompt photon cross section in [ital p[bar p]] collisions at [radical][ital s] =1. 8 TeV

A prompt photon cross section measurement from the Collider Detector at Fermilab experiment is presented. Detector and trigger upgrades, as well as six times the integrated luminosity compared with our previous publication, have contributed to a much more precise measurement and extended [ital P][su...

Beschreibung
Zusammenfassung:	A prompt photon cross section measurement from the Collider Detector at Fermilab experiment is presented. Detector and trigger upgrades, as well as six times the integrated luminosity compared with our previous publication, have contributed to a much more precise measurement and extended [ital P][sub [ital T]] range. As before, QCD calculations agree qualitatively with the measured cross section, but the data has a steeper slope than the calculations.
