We calculate the parameters describing elastic I=1, P-wave ππ scattering using lattice QCD with 2+1 flavors of clover fermions. Our calculation is performed with a pion mass of m[subscript π]≈320 MeV and a lattice size of L≈3.6 fm. We construct the two-point correlation matrices with both quark-anti...
