Description
In this talk I will review the recent analyses and other activities carried out by the JPAC collaboration. In particular, the phenomenological analysis of the $\eta^{(')} \pi$ partial waves measured at COMPASS. We fit the data using a coupled-channel amplitude based on first principles, determining in a robust way the existence of only one hybrid meson candidate $\pi_1$, corresponding to the $\pi_1(1600)$. We also extract the parameters of the ordinary mesons $a_2(1320)$ and $a'_2(1700)$.
