Description
We present a lattice QCD study of $\pi-N$ scattering in the iso-spin $I=3/2$ channel.
The calculation is performed using $N_f=2+1+1$ flavors of twisted mass fermions including an ensemble with
physical pion mass. We compute energy levels for all the moving frames with total momentum up to $\vec{P}=2\pi L(1,1,1)$,
and for all the relevant irreducible representation of the lattice symmetry groups.
We perform a phase-shift analysis including $S$ and $P$ wave phase shifts assuming a Breit-Wigner form of the resonance
in order to determine the parameters of the $\Delta$ resonance.
