We make a theoretical study of the J/Ψ decays into ωππ, φππ, ωKK̄ and φKK̄ using the techniques of the chiral unitary approach stressing the important role of the scalar resonances dynamically generated through the final state interaction of the two pseudoscalar mesons. We also discuss the importance of new mechanisms with intermediate exchange of vector and axial-vector mesons and the role playe...

We study the polarization of the J/ψ meson of the B̄c → J/ψ μ ν̄μ decay process, followed by J/ψ → μμ, with the help of the heavy-quark spin symmetry formalism (HQSS) of Jenkins et al. [1] We adapt the ISGW wave function. Due to the clean signature of the decay mode, measurements of the polarization of the J/ψ meson can play a special role in extracting |Vcb|, the quark mixing-matrix element. We ...

e + e − experiments producing charmonium are reviewed. It is found that the contribution of the continuum amplitude via virtual photon was neglected in almost all the experiments and the channels analyzed. It is shown that the contribution of the continuum part may affect the final results significantly in ψ(2S) and ψ(3770) decays, while the interference between continuum and resonance amplitud...

1 Why the OZI rule is so strongly violated in J/Ψ decays? The new f 0 (1790) meson recently observed by BES collaboration in J/Ψ-decay, is seen only in the OZI-forbidden channel. It is shown that chiral symmetry restoration in excited hadrons implies a new selection rule of dynamical origin that forbids some of the OZI-favoured mechanisms of decays. Hence decays into channels that are suppresse...

The CLEO-c research program will include studies of leptonic, semileptonic and hadronic charm decays, searches for exotic and gluonic matter, and test for physics beyond the Standard Model. The experiment and the CESR accelerator were modified to efficiently operate at center-of-mass energies between 3 and 5 GeV. Data at the ψ(3770) resonance were recorded with the CLEO-c detector in September ...
