Spin-parity structure of the (K pi pi )/sup 0/ system produced in the charge-exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/) n at 42 GeV/c

A partial wave analysis of the K/sup 0/ pi /sup +/ pi /sup -/ system produced in the charge exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/)n at 4.2 GeV/c has been performed both as a function of K pi pi mass and of t'. The 1/sup +/S wave forms the largest contribution to the K p...

description A partial wave analysis of the K/sup 0/ pi /sup +/ pi /sup -/ system produced in the charge exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/)n at 4.2 GeV/c has been performed both as a function of K pi pi mass and of t'. The 1/sup +/S wave forms the largest contribution to the K pi pi system and peaks at roughly the same mass as the Q in diffractive K pi pi production. The polarization properties of the 1/sup +/S(K* pi ) and 1/sup +/S(K rho ) waves differ from those of the diffractive 1/sup +/ wave. There is some evidence for a resonance contribution to 1/sup +/S(K* pi ). The strong 2/sup +/ wave is identified with K*(1420) and the K rho /K* pi decay branching ratio determined to be 0.36+or-0.10. An enhancement with spin-parity 1 /sup -/ is observed under the K*(1420). (14 refs).
