We also discuss the importance of new mechanisms with intermediate exchange of vector and axial-vector mesons and the role played by the OZI rule in the $\J\phi\pi\pi$ vertex, quantifying its effects. The results nicely reproduce the experimental data for the invariant mass distributions in all the channels considered. dc.language.iso eng dc.relation.ispartof International Journal of Modern Physics A, 2005, vol. 20, num. 8-9, p. 1897-1900 dc.rights.uri info:eu-repo/semantics/openAccess dc.source Roca Zamora, Luis Palomar Burdeus, Juan Esteban Oset Báguena, Eulogio Chiang, H.C. 2005 Unitary chiral dynamics in J/Psi decays into VPP and the role of the scalar mesons International Journal of Modern Physics A 20 8-9 1897 1900 dc.subject Física dc.title Unitary chiral dynamics in J/Psi decays into VPP and the role of the scalar mesons dc.type info:eu-repo/semantics/article dc.date.updated 2015-09-08T07:38:11Z dc.identifier.doi http://dx.doi.org/10.1142/S0217751X0502358X dc.identifier.idgrec 025711
