Description
The COMPASS experiment at CERN's SPS provides a very large data set to study the
light-meson spectrum in diffractive production reactions of 190$\,$GeV$/\text{c}$ beam pions with protons. Among the many different final states accessible, $\eta\pi^-$ and $\eta^{\prime}\pi^-$ are clean channels to investigate the lightest hybrid-meson candidate, the $\pi_1(1600)$. One challenge in the extraction of resonance parameters, like pole positions, is the separation of resonant and non-resonant processes.
To better constrain the non-resonant production mechanism of these final states, we analyze the high-mass region, i.e. $4\,\text{GeV}/\text{c}^2
