Description

Starting from hyperbolic dispersion relations for the invariant amplitudes of pion–nucleon scattering together with crossing symmetry and unitarity, we derive a closed system of integral equations for the partial waves of both the s-channel (\pi N->\pi N) and the t-channel (\pi\pi→\bar N N) reaction, called Roy–Steiner equations. We also solve the t-channel subsystem by means of Muskhelishvili–Omnès techniques and present preliminary results on the solution of the s-channel problem.
