# Study of the $f_2(1270)$, $f_2'(1525)$, $f_0(1370)$ and $f_0(1710)$ in the $J/\psi$ radiative decays

## TL;DR

This paper investigates the radiative decay modes of the $J/ar{psi}$ into various tensor and scalar mesons, comparing dynamical generation models with quark models to identify potential distinguishing features.

## Contribution

The study compares predictions from dynamical vector meson scattering models and quark models for $J/ar{psi}$ radiative decays into specific mesons, suggesting ways to differentiate these scenarios.

## Key findings

- Evidence that improved data could distinguish models
- Comparison of dynamical and quark model predictions
- Insights into meson structure from decay patterns

## Abstract

In this paper we present an approach to study the radiative decay modes of the $J/\psi$ into a photon and one of the tensor mesons $f_2(1270)$, $f'_2(1525)$, as well as the scalar ones $f_0(1370)$ and $f_0(1710)$. Especially we compare predictions that emerge from a scheme where the states appear dynamically in the solution of vector meson--vector meson scattering amplitudes to those from a (admittedly naive) quark model. We provide evidence that it might be possible to distinguish amongst the two scenarios, once improved data are available.
