      Petschlies, Marcus; Alexandrou, Constantia; Leskovec, L.; Meinel, S.; Negele, J.; Paul, S.; Pochinsky, A.; Rendon, G.; Syritsyn, S. (2017)
      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 mπ≈320 MeV and a lattice size of L≈3.6 fm. ...
