Amplitude and natural-parity-exchange analysis of K±p → (Kπ)±p data at 10 GeV/c

High statistics data for the reactions K^±p → K_S⁰π^±p at 10 GeV/c are analysed. The K¹(1^?), K¹(2⁺), and K¹(3^?) resonance parameters and production cross sections are calculated. The Kπ production amplitudes are determined as a function of t and the produced Kπ mass. Isoscalar natural-parity-exchange (NPE) is dominant. The t dependence of the K^± NPE amplitudes have a cross-over at t = ?0.3 (GeV/c)² for both K¹(890) and K¹(1420) production, being more pronounced for the K¹(1420). Natural-parity-exchange interference effects are isolated. The NPE amplitudes are decomposed into pomeron-, f-, and ω-exchange contributions. S-wave Kπ production is found to be consistent with the Kπ partial-wave analyses of charge-exchange reactions.
