Low energy Eta-baryon interaction

Abstract

The $\eta$-Baryon interactions at low energies are studied in a model based in effective chiral Lagragians that take into account baryons of spin 1/2 and spin 3/2 in the intermediate states. The interacting baryons to be considered in this work are $B= N, \Lambda, \Sigma, \Xi$. We calculate the expected total and differential cross sections, phase-shifts and polarizations in the center-of-mass frame of reference for each reaction.
