Recent progress in the partial-wave analysis of the diffractively produced $\pi^-\pi^+\pi^-$ final state at COMPASS
The Compass spectrometer at CERN has collected a large data set for diffractive three-pion production of 46 × 106 exclusive events. Based on previous conventional Partial-Wave Analyses (PWA), we performed a “freed-isobar PWA” on the same data, removing model assumptions on the dynamic isobar amplitu...
