Systematic few-body analysis of eta-d, eta-3He and eta-4He interaction at low energies
A. Fix, O. Kolesnikov
The Alt-Grassberger-Sandhas N-body theory is used to study interaction of eta-mesons with d, 3He, and 4He. Separable expansion of the subamplitudes is adopted to convert the integr…

Solution of the eta-4He problem with quasi-particle formalism
A. Fix, O. Kolesnikov
The Alt-Grassberger-Sandhas equations for the five-body eta-4N problem are solved for the case of the driving eta N and NN potentials limited to s-waves. The quasi-particle (Schmid…
