Unitarity approach to the mass-dependent fit of $3\pi$ resonance production data from the COMPASS experiment
We derive a unitarized model for the peripheral production of the three-pion system in the isobar approximation. The production process takes into account long-range t-channel pion exchange. The K-matrix approach is chosen for the parameterization of the scattering amplitude. Five coupled channels a...
