Direct determination of the total width of the eta prime meson using the COSY-11 apparatus

Abstract

We describe the experimental method and consecutive steps of the analysis of the pp-->pp eta prime reaction measured by means of the COSY-11 detection setup. The conducted investigation aim at the determination of the total width of the eta prime meson directly from its mass distribution. The preliminary results show that the statistical error is in the order of ~10 keV.
