Light isovector resonances in $π^{-} p \to π^{-} π^{-} π^{+} p$ at 190 GeV/ $c$

M. Aghasyan, M. G. Alexeev, G. D. Alexeev +221

We have performed the most comprehensive resonance-model fit of $π^{-} π^{-} π^{+}$ states using the results of our previously published partial-wave analysis (PWA) of a large data set of…

New analysis of $η π$ tensor resonances measured at the COMPASS experiment

A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232

We present a new amplitude analysis of the $η π$ $D$ -wave in $π^{-} p \to η π^{-} p$ measured by COMPASS. Employing an analytical model based on the principles of the relativistic $S$ -mat…
