  • Isoscalar ππ Scattering and the σ Meson Resonance from QCD 

    Briceño, RA; Dudek, JJ; Edwards, RG; Wilson, David John (American Physical SocietyPhysical Review Letters, 2017-01-13)
    We present for the first time a determination of the energy dependence of the isoscalar ππ elastic scattering phase shift within a first-principles numerical lattice approach to QCD. Hadronic correlation functions are ...
