      P -wave ππ scattering and the ρ resonance from lattice QCD 

      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. ...

      A study of the radiative transition ππ → πγ∗ with lattice QCD 

      Petschlies, Marcus; Leskovec, L.; Alexandrou, Constantia; Koutsou, Giannis; Meinel, S.; Negele, J. W.; Paul, S.; Pochinsky, A.; Rendon, G.; Syritsyn, S. (Proceedings of Science (PoS), 2016)
      Lattice QCD calculations of radiative transitions between hadrons have in the past been limited to processes of hadrons stable under the strong interaction. Recently developed methods for 1 → 2 transition matrix elements ...
