Low-energy pion-nucleon scattering and the Δ resonance in lattice QCD
Low-energy pion-nucleon scattering and the Δ resonance in lattice QCD
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...

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, using the Lüscher finite-volume method to extract the phase shift $\delta_{J=3/2,l=1}$ |
