A2− production in the reaction π−p → K−KS0p at 9.8 and 18.8 GeV

Abstract

Abstract Results of two spark chamber experiments on A2− production in the reaction π−p → K−KS0 (→ π+π−)p at 9.8 and 18.8 GeV are presented. Decay angular distributions and differential cross sections are given, and the energy dependence of the cross section σ[π−p → A2−(→ K−K0)p] is compared with results from π−p → A2−(→ 3π)p.
