EVIDENCE FOR ANOMALOUS PROMPT PHOTONS IN DEEP INELASTIC MUON SCATTERING AT 200-GEV

Abstract:
The inclusive yield of photons has been measured from deep inelastic interactions of 200 GeV muons on hydrogen. After subtracting the contributions from hadron electromagnetic decays and Bethe-Heitler muon bremsstrahlung, residual photons are observed at low pT and low z at a mean level of 0.15±0.06 per interaction. The quark Compton scattering process is unable to explain the data, thus indicating an anomalous photon production. © 1989.
