Elastic Nucleon-Pion scattering amplitudes in the $\Delta$ channel at physical pion mass from Lattice QCD

Constantia Alexandrou, Simone Bacchio, Giannis Koutsou +4

We present an investigation of pion-nucleon elastic scattering in the $I(J^P)=\frac{3}{2}({\frac{3}{2}}^{+})$ channel using lattice QCD with degenerate up and down, strange and c…
