Lattice study of pion-pion scattering using Nf=2+1 Wilson improved quarks with masses down to their physical values

Thibaut Metivet

We use 2HEX smeared gauge configurations generated with an ${\mathrm{N}}_{\mathrm{f}}=2+1$ clover improved Wilson action to investigate $\pi \pi$ scattering in the $\rho$ channel. The…
