Abstract
Abstract
The hyperbolic version of Roy-Steiner equation describing low energy πN scatterings, with larger analyticity domain in the complex s plane is solved. The numerical results on phase shifts of low partial waves are in agreement with that of Hoferichter et al. [Phys. Rept.625 (2016) 1]. A subthreshold pole in S11 channel is found located at $$ \sqrt{s} $$
s
= (918 ± 3) − i(163 ± 9) MeV.
