Study of K*-(890) and K*-(1430) production in the reaction K-p-->K¯0π-p at 100 and 175 GeV/c
Abstract
The reaction K-p-->K¯0π-p has been studied at 100 and 175 GeV/c and the reaction π-p-->K0K-p at 50, 100, and 175 GeV/c. Both reactions are dominated by production of resonances, K*(890), K*(1430) and A2(1320), A2(2040), respectively. Production cross sections, t distributions, and decay-angular distributions are studied. Isoscalar natural-parity exchange is dominant. The energy dependence of the K* and A2 resonance production between 10 and 175 GeV/c is well described by a Regge-pole model. Our data on A2 corrects that in an earlier paper.
