Studies of Properties of the η‧ Meson at the COSY-11 Facility
Abstract
We shortly discuss results on the isospin dependence of the η‧ production cross section in nucleon-nucleon collisions, results of comparative analysis of the invariant mass distributions for the pp → ppη‧ and pp → ppη reactions, and we present the value of the total width of the η‧ meson as derived directly from the mass distribution measured with the mass resolution of 0.3 MeV/c2.
