Description
We present some results on the analysis of $3\pi$ resonances from peripheral scattering of pions off of nuclear targets. The light meson sector is rich with states that can be accessed through three pions. In the modern search for exotic mesons, it is important to understand how to extract resonances in these channels. The analysis is motivated by the recent release of the largest data set on diffractively produced three pions by the COMPASS collaboration. The model emphasizes the $3\pi$ production process and their final state interactions which satisfy $S$-matrix principles. We apply our model to the recent results from the COMPASS experiment. We develop the model for partial waves, and focus on the $J^{PC}=2^{-+}$ sector and search for resonances.
