Observation of a soft photon signal in excess of QED expectations in pp interactions

Photons produced in pp interactions at 450 GeV/c were detected by reconstructing the e/sup +/e/sup -/ pairs of photon conversions in a 1 mm thick lead sheet placed in front of the MWPCs of the OMEGA spectrometer at CERN. A soft photon signal 4.1 +or- 0.8 times the inner bremsstrahlung prediction was...
