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