نویسنده
چکیده
We consider the impact of two recent π − p → ηn measurements on the ηN scattering length and ηN branching fractions for the N (1535) and N (1520) resonances within a coupled-channel analysis of πN elastic scattering and ηN production data. The sensitivity of these results to model input is also explored.

Our contribution to the Eta’05 workshop on “Production and Decay of η and η Mesons” (1518.9.2005, Cracow, Poland) is summarized. First we discuss open questions in the theoretical treatment of Coulomb-interaction in the context of reaction processes like pp → ppη. Then we review η-η and σ(600)-f0(980) mixing in the U(3)×U(3) Linear Sigma Model and extract information on η-η mixing and the K 0 (...

The fascinating physics underlying η and η′ mesons can be studied theoretically and experimentally in various contexts. In this presentation we want to turn our attention to two important uncorrelated aspects of this vivid research field which provide yet unexpected challenges or surprises. First we discuss open questions in the theoretical treatment of Coulombinteraction in the context of reac...

The presently available data for the reaction γp→η ′ p are analyzed in terms of a model in which the dominant production mechanism is the exchange of the vector mesons ω and ρ. To describe the data at photon energies close to the production threshold we introduce a resonance contribution due to the well established S 11 (1535) resonance. Finally we study the contributions due to nucleon exchang...
