P. G. Moreira, M. L. L. da Silva
TL;DR
This paper investigates the glue content of the $f_1(1285)$ meson by calculating its radiative decay to vector mesons using a non-relativistic approach, comparing results with experimental data to estimate its gluonic component.
Contribution
It provides a comparative analysis of the glue content of $f_1(1285)$ based on different experimental datasets, highlighting the dependence on data sources.
Findings
Small or negligible glue content when compared to PDG data.
Large glue content when compared to CLAS data.
Highlights the sensitivity of glue content estimates to experimental data used.
Abstract
The radiative decay of to vector mesons and is calculated in a non-relativistic approach. The results obtained are compared to experimental data to estimate the glue content of . We find a small or nonexistent glue content when our results are compared to the PDG data. However a large glue content for was found when we compared our results to the CLAS data.
