Differential cross section of the reaction π + +p→K + +Y (1385) at 4.0 and 5.05 GeV/c

Approximately 1900 events were obtained in the differential cross section measurements of the reaction π + +p→K + +Y * (1385). Forward peaks were found with slopes of 2.3 ± 0.3 and 2.6 ± 0.4 (GeV/ c) −2 for 4 and 5.05 GeV/ c respectively. This data together with that in other decuplet production rea...

Description
Summary:Approximately 1900 events were obtained in the differential cross section measurements of the reaction π + +p→K + +Y * (1385). Forward peaks were found with slopes of 2.3 ± 0.3 and 2.6 ± 0.4 (GeV/ c) −2 for 4 and 5.05 GeV/ c respectively. This data together with that in other decuplet production reactions gives evidence of a large SU(3) violation as would be expected from the mass splitting of the strange and non-strange exchanged particles.
