Analysis of the diffractively produced $\pi^-\pi^-\pi^+$ Final State at COMPASS


  • Mr. Florian KASPAR

Primary authors


The COMPASS experiment at CERN collected a large sample of diffractively produced $\pi^-\pi^-\pi^+$ events. The data contain signals from iso-vector resonances decaying into $\pi^-\pi^-\pi^+$. We extract the resonance signals by performing a detailed partial-wave analysis in bins of three-pion mass and squared four-momentum transferred from the beam to the target.

In this talk, we will present and discuss selected results of this analysis.
