Study of the f2(1270) , f2′(1525) , f0(1370) and f0(1710) in the J/ψ radiative decays

Combining heavy quark spin and local hidden gauge symmetries in the dynamical generation of hidden charm baryons

“…The properties of the resonances obtained are shown to be consistent with the radiative decay to two photons [12] and to two-photon and one photon-one vector meson in [13]. Similarly, consistency with experiment has been shown in J/ψ → φ(ω)R [14], with R any of the resonances of [11], and in J/ψ radiative decays in [15]. The extension of these ideas to the charm and hidden charm sector have also shown that some of the excited D states and X,Y,Z states recently reported could be explained in terms of molecules involving mesons with charm [16][17][18][19][20][21][22].…”

“…Another successful test on the vector-vector nature of the f 2 (1270) and f ′ 2 (1525) was done in Ref. [14] by looking at the decay of J/ψ into γT , where T is any of these two tensor resonances. A justification was given in Ref.…”

“…A justification was given in Ref. [14] for the photon being radiated from the initial cc state. The remaining cc gave rise to a pair of vector mesons which upon rescattering produced the tensor resonances.…”

“…At the same time, in this latter work the ideas of Ref. [14] in the radiative decay were extended to the decay of Υ(1S), Υ(2S) and ψ(2S). These hadronic and radiative decays for J/ψ have also been addressed within a scheme where the f 0 (1370), f 0 (1500) and f 0 (1710) states emerge as a result of glueball quarkonia mixing [16].…”

“…Related work was also done in Ref. [14] interpreting the J/ψ radiative decay into these resonances. Those latter works were then extended in Ref.…”
