Abstract
By applying a unitary transformation to the Lagrangian density of the cloudy-bag model, the author obtains a generalisation of the Weinberg effective Lagrangian for pion-nucleon scattering. The new Lagrangian incorporates the Weinberg-Tomozawa result for s-wave pion scattering from any hadronic bag in a very simple but elegant fashion.Keywords
