Triangle Singularity as the Origin of the $a_{1} (1420)$

G. D. Alexeev, M. G. Alexeev, A. Amoroso +194

The COMPASS experiment recently discovered a new isovector resonance-like signal with axial-vector quantum numbers, the $a_{1} (1420)$ , decaying to $f_{0} (980) π$ . With a mass too close…

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…
