Eb. Berdnikov et al., LATEST RESULTS FROM THE VES EXPERIMENT, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 107(10), 1994, pp. 1941-1951
We present here the results of the VES experiment obtained in 1992-199
3: 1) The partial-wave analysis (PWA) has been performed for the react
ions pi(-) N --> eta pi(-) N and pi(-) N --> eta pi(-) N. It has been
shown that the intensity of the exotic wave with J(PC) = 1(-)+ for the
eta(')pi(-) system significantly exceeds that for the eta pi(-) syste
m. 2) The PWA has been performed for the reactions pi(-) N --> pi(+) p
i(-)pi(-) N and pi(-) N --> K+K- pi(-) N. The resonance at m = 1.8 GeV
with J(PC) = 0(-)+ is clearly seen in both reactions. 3) The radiativ
e decay f(1) --> pi(770)gamma has been studied. The measured BR(f(1)(1
285) --> rho(0)(770)gamma) = (3.0 +/- 0.7(stat) +/- 0.6(syst)).10(-2).
