Low energy pion–$$\Lambda _b$$ interaction

Abstract

AbstractThe 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.
