# Radiative decays of $f_1(1285)$ as the $ K^*\bar K$ molecular state

## TL;DR

This paper models the $f_1(1285)$ meson as a $K^*ar K$ molecular state and estimates its radiative decay rates to vector mesons, aligning well with experimental data and offering testable predictions.

## Contribution

It provides a novel molecular interpretation of $f_1(1285)$ and calculates its radiative decay rates using kaon loop diagrams, which are consistent with observations.

## Key findings

- Calculated decay rates agree with experimental data
- Predictions for unmeasured decays are provided
- Supports the molecular state hypothesis for $f_1(1285)$

## Abstract

Within a picture of the $f_1(1285)$ being a dynamically generated resonance from the $ K^*\bar K$ interactions, we estimate the rates for the radiative transitions of the $f_1(1285)$ meson to the vector mesons $\rho^0$,$\omega$ and $\phi$. These radiative decays proceed via the kaon loop diagrams. The calculated results are in fair agreement with the experimental measurements. Some predictions can be tested by experiments and their implementation and comparison with these predictions will be valuable to decode the nature of the $f_1(1285)$ state.
