Investigating the glue content of f(1) (1285)

摘要

The radiative decay of f(1)(1285) to vector mesons rho and phi is calculated in a non-relativistic approach. The results obtained are compared to experimental data to estimate the glue content of f(1). We find a small or nonexistent glue content when our results are compared to the PDG data. However a considerable glue content for f(1) (1285) was found when we compared our results to the CLAS data. (C) 2019 Elsevier B.V. All rights reserved.
