Nn. Achasov et Aa. Kozhevnikov, ISOSCALAR RESONANCES WITH J(PC)=1(--) IN E(-) ANNIHILATION()E(), Physical review. D. Particles and fields, 57(7), 1998, pp. 4334-4342
The analysis of the vector isoscalar excitations in the energy range b
etween 1 and 2 GeV of the e(+)e(-) annihilation is presented for the f
inal states pi(+)pi(-)pi(0), omega pi(+)pi(-), K+K-, K(S)(0)K(+/-)pi(-
/+), and K(0)K(-)pi(+) + c.c. The effects of both resonance mixing an
d the successive opening of multiparticle channels, with energy-depend
ent partial widths, are taken into account. The work extends our previ
ous analysis of vector isovector excitations and is aimed at comparing
the existing data with the predictions of the q (q) over bar model. I
t is shown that this hypothesis does not contradict the data. [S0556-2
