Confirmation of a soft photon signal in excess of Q.E.D. expectations in $\pi^- p$ interactions at 280 GeV/c
Photons produced in \pip 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\pm 1.6$ times the Q.E.D....

description | Photons produced in \pip 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\pm 1.6$ times the Q.E.D. inner bremsstrahlung prediction was observed confirming the results of a previous experiment. |
