Scattering Amplitude of πN on the Second Sheet [PDF]
Mohamed E. KelabiWe propose parameterization procedures of the scattering amplitude f_{1+}^{3}(s)) with a view to extracting the pole parameters from data in the elastic region of {\pi}N scattering. This is achieved by considering the analyticity properties of partial wave amplitudes directly and writing dispersion relations for the amplitude explicitly.View original: http://arxiv.org/abs/1302.3891
