TL;DR: In this paper, a measurement of the direct production of photons with high transverse momentum from collisions at δ(n ϵ s = 630 ϵ GeV ) was presented.
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.
