J/ψ decay to ϕ,ω,K⁎0 plus f0(1370), f0(1710), K0⁎(1430), f2(1270), f2′(1525) and K2⁎(1430): Role of the D-wave for tensor production

We reassess the decay of the J/ψ into an ω,ϕ,K and one of the f(1370), f(1710), f(1270), f(1525), K(1430) and K(1430) resonances. We benefit from previous works that considered this reaction as a J/ψ decay into three vector mesons, with a scalar or tensor resonance being formed from the interaction...

Sumario:We reassess the decay of the J/ψ into an ω,ϕ,K and one of the f(1370), f(1710), f(1270), f(1525), K(1430) and K(1430) resonances. We benefit from previous works that considered this reaction as a J/ψ decay into three vector mesons, with a scalar or tensor resonance being formed from the interaction of two of these vectors. The novelty here with respect to former studies is the investigation of the relation between the scalar meson and tensor productions for the first time. To this end, the spin structure of the four vectors present in the production vertex is analyzed, and the D-wave mechanism in the tensor production is included. Then, beyond the ratios studied previously involving scalar states and tensor states independently, new ratios relating the scalar and tensor meson productions are estimated. Our results suggest that the D-wave mechanism of tensor production assumes a relevant contribution. New experimental data reporting the angular distributions of these processes will be important for checking this conclusion.
