Direct photon
text:
Produced in hadronic collisions, a direct photon is any real photon which originates directly from an electromagnetic vertex in a quark-quark, quark-gluon or gluon-gluon scattering subprocess. Because the QCD calculations for direct photon production are considerably easier to perform than for other processes studies of direct photons have been used to test predictions made by perturbative QCD. Direct photons were predicted to exist by C.O. Escobar in 1975 and were first observed by the R412 gro
