Description

We study the χc1 → ηπ+π- decay, paying attention to the production of f0(500), f0(980), and a0(980) from the final state interaction of pairs of mesons that can lead to these three mesons in the final state, which is implemented using the chiral unitary approach. Very clean and strong signals are obtained for the a0(980) excitation in the ηπ invariant mass distribution and for the f0(500) in the π+π- mass distribution. A smaller, but also clear signal for the f0(980) excitation is obtained. The results are contrasted with experimental data and the agreement found is good, providing yet one more test in support of the picture where these resonances are dynamically generated from the meson-meson interaction.
