Description
Summary:Abstract The low energy pion–$$\Lambda _b$$ Λb interaction is study in this work, considering effective chiral Lagrangians that include pions, baryons and the corresponding resonances. Interactions mediated by a $$\sigma $$ σ meson exchange are also considered. The scattering amplitudes are calculated and then we determine the angular distributions and polarizations.
