Comparison of PWA results of K(sup +)K(sup o)(sub s) pi(sup (minus)) final states produced in 8 GeV/c K(sup (minus))p, pi(sup (minus)) p and (bar p)p interactions

摘要

We have performed partial-wave analyses of the K(sup +)K(sup o)s (pi)(sup (minus)) system produced in the reactions K(sup (minus))p (yields) K(sup +)K(sup o)s(pi)(sup (minus)), (Lambda)/(Sigma), (pi)(sup (minus))p (yields) K(sup +)K(sup o)s (pi)(sup (minus))n and (bar p)p (yields) K(sup +)K(sup o)s(pi)(sup (minus)) X at 8 GeV/c in substantially the same apparatus. We present and compare the results of the analysis of the three reactions in the mass range 1.24 GeV/c(sup 2) < M(KK(pi)) <1.56 GeV/c(sup 2). In all three reactions the J(sup PG) = O(minus plus), 1(plus minus) and 1(sup ++) waves are the most important. A strong f(sub 1)(1285) signal is evident in the (pi) and (bar p) beam data sets but not in the K data. There is evidence of (eta)(l280) production, especially in the n and 0 beam data. We find evidence of two O(sup (minus plus)) states in the 1400 MeV/c(sup 2) mass region, but no compelling case for a 1(sup ++) resonance in this region. Finally, the 1(sup (plus minus)) wave in the K beam data is consistent with an h' state below the K*K threshold.
