Confirmation of a soft photon signal in excess of Q.E.D. expectations in π−p interactions at 280 GeV/ c

Photons produced in π −p interactions at 280 GeV/ c were detected by reconstructing the e +e − pairs produced via the materialisation of the photons in a 1 mm thick lead sheet placed in front of the MWPC's of the OMEGA spectrometer at CERN. A soft photon signal 7.8 ± 1.5 times the Q.E.D. inner...

Description
Summary:Photons produced in π −p interactions at 280 GeV/ c were detected by reconstructing the e +e − pairs produced via the materialisation of the photons in a 1 mm thick lead sheet placed in front of the MWPC's of the OMEGA spectrometer at CERN. A soft photon signal 7.8 ± 1.5 times the Q.E.D. inner bremsstrahlung prediction was observed confirming the results of a previous experiment.
