Study of ${\eta }^{\prime }\to \eta {\pi }^{+}{\pi }^{-}$ Dalitz plot

Abstract

Dalitz plot of the ${\eta }^{\prime }\to \eta {\pi }^{+}{\pi }^{-}$ decay is studied using the data collected with the VES spectrometer in two different exclusive reactions. The coefficients for the matrix element squared decomposition are measured on the largest statistics of ${\eta }^{\prime }$ decays reported so far.
