Description
We report on our investigation of low-energy pion-nucleon scattering from lattice QCD with Wilson-type fermions.
Our focus is on the isospin $I=3/2$ channel, which couples to the Delta resonance.
We discuss our calculations aiming at the extraction of the Delta resonance mass, width and effective coupling at pion mass
$250$ MeV and the physical point, using the L\"uscher finite-volume method to extract the phase shift $\delta_{J=3/2,l=1}$.
