Description
We review the determination of the low-energy pion-nucleon scattering amplitude using Roy-Steiner equations. In particular, we focus on the phenomenological determination of the pion-nucleon $\sigma$-term, derived in combination with modern precision data on pionic atoms. We will also discuss recent applications to nucleon form factors and the determination of low-energy constants in chiral perturbation theory.
