Descripción
I will talk about a generalization of effctive range expansion with a left-hand cut due to the t- or u-channel exchange of a particle with a small finit mass. The generalization is constructed using the N/D method of dispersion theory and has a Pade-like form. The applicability will be shown by extracting the NNpi coupling from NN scattering phase shifts using this formalism.
