| dc.description.abstract | We study the four-body decays J/psi --> N(N) over bar meson meson using a chiral unitary approach to account for the meson meson final state interaction (FSI). The calculation of the J/psi --> N(N) over bar pi(+)pi(-) process properly reproduces the experimental data after taking the FSI of mesons and the contribution of intermediate rho meson into account. The isoscalar resonances sigma,f(0)(980) and the isovector resonance a(0)(980) are generated through the FSI of the mesons in the channels J/psi --> N(N) over bar pi(0)pi(0) and J/psi --> N(N) over bar pi(0)eta, respectively. We also calculate the two mesons invariant mass distribution and the partial decay width of J/psi --> N(N) over barK(+)K(-) and J/psi --> N(N) over barK(0)(K) over bar (0), on which there is still no experimental data available. | |
