Observation of a narrow minimum and of inelastic shadow effects in deuteron-deuteron elastic scattering at √s = 53 GeV
1978
Abstract We report on experimental results on deuteron-deuteron elastic scattering at a centre-of-mass energy of √ s = 53 GeV . The data were obtained using the Split Field Magnet detector at the CERN intersecting Storage Rings. The t -dependence of the elastic cross section is measured up to − = 1.5 GeV 2 . We observed a narrow interference minimum in the differential cross section at − = 0.18 GeV 2 . The inclusion of inelastic intermeduate states in the multiple scattering Glauber theory is essential in the description of the data over the entire t -range where discrepancies of up to 25% are observed with the basic theory.
