Measurement of the decay $η^{'} \to π^{0} π^{0} η$ at MAMI

P. Adlarson, F. Afzal, C. S. Akondi +75

An experimental study of the $η^{'} \to π^{0} π^{0} η \to 6 γ$ decay has been conducted with the best up-to-date statistical accuracy, by measuring $η^{'}$ mesons produced in the $γ p \to η^{'} p$ re…

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…
