Abstract

The η production is characterized by a strong cross section close to the threshold. The S11 nucleon resonance has a specific role in this domain with important consequences below the elementary threshold. The mass of the η, well above the π mass, provides interesting informations on the sharing of the momentum transfered in reactions involving a small number of nucleons. The η production as a possible source of e + e is also studied in the context of dileptons produced by heavy ion collisions of a few GeV per nucleon. As a practical consequence, the production of η from baryonic interaction is now used to study the physics of η decays.

A short review of the present knowledge and activities on the η production from hadronic interaction in the energy range of 1–2 GeV is discussed with both experimental and theoretical aspects.
