A partial-wave analysis (PWA) of the J/psi-->gamma-K(S)0K+/-pi-/+, gamma-K+/-K-/+pi-0 decays in the iota/eta(1430) mass range shows a clear pseudoscalar dominance, with two dynamical components both above 1400 MeV/c2 which proceed via a0(980)pi and K*(892)K dynamics, respectively. In addition, a significant contribution from the 1++ K*(892)K wave is contained in the higher part of the mass spectrum. In the PWA of the J/psi-->gamma-eta-pi+-pi-channel a resonant a0-pi production is observed but slightly below 1400 MeV/C2.

Abstract

A partial-wave analysis (PWA) of the J/psi-->gamma-K(S)0K+/-pi-/+, gamma-K+/-K-/+pi-0 decays in the iota/eta(1430) mass range shows a clear pseudoscalar dominance, with two dynamical components both above 1400 MeV/c2 which proceed via a0(980)pi and K*(892)K dynamics, respectively. In addition, a significant contribution from the 1++ K*(892)K wave is contained in the higher part of the mass spectrum. In the PWA of the J/psi-->gamma-eta-pi+-pi-channel a resonant a0-pi production is observed but slightly below 1400 MeV/C2.
