In this paper, we study the spectrum and decay behavior of $5^{++}$ meson family which is still missing in experiment. By the modified Godfrey-Isgur model with a color screening effect, we obtain the mass spectrum of $a_5$, $f_5$ and $f_5^\prime$ mesons. And we predict their two-body strong decays by means of a phenomenology quark pair creation model. This study is crucial to establish $J^{PC}=5^{++}$ meson family and it is also helpful to search for these states in the future.

  1. Comparing relativistic and non-relativistic quark pair creation models

    Relativistic and non-relativistic QPC models produce strong decay width predictions of similar overall quality for light mesons, with the relativistic version exhibiting stronger suppression at high energies.
