Final state interaction in the reaction NN -> eta NN
Abstract
The production of η mesons in NN collisions in the near threshold region is analyzed with special emphasis on the role of final state interaction which is calculated using three-body scattering theory. The three-body aspects are shown to be very important in interpreting experimental results for the total cross section of ppη pp. Furthermore, energy spectra and angular distributions of the emitted particles are calculated and compared to experimental data.
