Diffractive Dissociation into $\pi^{-}\pi^{-}\pi^{+}$ Final States at COMPASS
Diffractive dissociation reactions studied at the COMPASS experiment at CERN provide access to the light-meson spectrum. During a pilot run in 2004, using a pion beam and a lead target, 420k $\pi^{-}\pi^{-}\pi^{+}$ final-state events with masses below 2.5 GeV/c$^{2}$ were recorded, yielding a signif...
