Direct photon production in\(\bar pp\) in collisions at\(\sqrt s = 630\) GeV

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A measurement of the direct production of photons with high transverse momentum from\(\bar pp\) collisions at\(\sqrt s = 630\) GeV is presented. The structure of events containing a high transverse momentum photon is studied. The results support predictions from QCD theory.
