ANALYSIS OF TWO PARTICLE SYSTEMS FROM A TRIGGERED HYBRID BUBBLE CHAMBER EXPERIMENT
Abstract
Analyses of the final states k('+) (')k('0) p, k('+) (pi)('+) (LAMDA), and p n p resulting from (pi)('+) p interactions at 11.5 GeV/c are presented for data obtained from a triggered hybrid bubble chamber experiment. In addition, the cross sections are calculated and discussed for other reactions which do not contain fast downstream pions. A partial wave analysis of the di-kaon system in the k('+) (')k('0) p final state reveals the dominance of the D(,+) and P(,+) partial waves in the A(,2)(1310) mass region. Spin analysis of the pi-lambda system in the k('+) (pi)('+) (LAMDA) final state suggests that single Regge exchange is insufficient to explain the data in the (SUMM)(1385) region and therefore supports both k*(890) and k*(1430) exchange. Finally, analysis of the p n system in the p n p final state indicates high spin resonance production near threshold which is not consistent with the simple OPE model.
