The annihilation process pp → π0ω at rest in liquid and gaseous hydrogen Original Research Article

The preliminary analysis of the reaction View the MathML source (ω → π+π−π0) at rest, both in liquid and NTP gaseous hydrogen targets, performed with the Obelix apparatus is presented. The values of the measured annihilation frequencies and the study of the angular distributions of the decay products have been used to investigate the initial state distributions of the annihilation and the OZI rule violation.
