Feasibility study of the eta-prime -> pi+pi-pi0 decay using WASA-at-COSY apparatus collisions of protons we discuss in details the feasibility of a measurement of the eta-prime meson decay into 3pi channels with the WASA-at-COSY ... ...
η meson decaysleptonic decaysThe search for the decay eta --> e+e- was carried out using the WASA detector at the COSY storage ring. Data were taken during a two week experimental run in Sept-Nov 2008 in which about 107 eta mesons were collected from the reaction of pp --> ppeta ...
The nature of η-meson-nuclear interactions is even more exciting, since the η lifetime allows it to leave the nucleus prior to decay. As η mesons is an isoscalar particle, it can only couple with isospin — 1/2N∗ resonances, on the contrary with isovector mesons like π0 and ρ...
Since the eta meson is a short-lived neutral particle, it is not possible to investigate its structure via classical methods of particle scattering. To learn about its quark wave function, one studies those decay processes of this meson in which a pair of photons is produced, where at least...
Weak Particle DecayMeetingsThe ETA collaboration is now building a large acceptance detector to investigate multiparticle decays of the (eta) meson and a few aspects of the Physics program are discussed. The perspectives of new researches on (eta) decays with a large acceptance detector are ...

We analyse SU(3) × SU(3) breaking effects for η→γγ decay. Besides those induced by the η-η′ mixing, we find that the quark loop contribution could increase the amplitude and compensate largely for a reduction by the SU(3) breaking in the η meson decay constant. The measured ...
