The width of the f1(1285) → e+e+e- decay is calculated in the vector meson dominance model. The result depends on the relative phase between two coupling constants describing f1 → ρ0γ decay. The width Γ( f1 → e+e+e-) is estimated to be ≃ 0:07 - 0:19 eV. Direct f1 production in e+e+e- collisions is discussed, and the e+e+e- → f1 → a0π → ηππ cross section is calculated. Charge asymmetry in the e+e+e- → ηπ+π- reaction due to interference between e+e+e- → f1 and e+e+e- → ηρ0 amplitudes is studied.

Chiral Lagrangian

The octet meson and baryon interaction with strangeness [Formula: see text] is studied fully relativistically with chiral Lagrangian. In this paper, a Bethe–Salpeter equation (BSE) approach with spectator quasipotential approximation is applied to study the reactions [Formula: see text] with [Formula: see text] and [Formula: see text] with all possible partial waves and theoretical results are comparable with experimental data. It is found that the Weinberg–Tomozawa potential derived from the lowest order chiral Lagrangian only provides the contributions from partial waves with spin-parities [Formula: see text] and [Formula: see text]. Two-pole structure of the [Formula: see text] is confirmed with poles at [Formula: see text] and [Formula: see text] MeV. The lower and higher poles originate from [Formula: see text] interaction as a resonance and [Formula: see text] interaction as a bound state, respectively.

Vector Meson Exchange

The hyperon-nucleon scattering processes and some dibaryon states are studied both in the chiral SU(3) quark model and in the extended chiral SU(3) quark model by solving the resonating group method (RGM) equation. We find that the short-range interaction could be described either by the one-gluon exchange or by the vector meson exchange for baryon-baryon system.
