The energy-dependent ${\pi }^{+}{\pi }^{+}{\pi }^{+}$ scattering amplitude from QCD

Maxwell T. Hansen, Raul A. Briceño, Robert G. Edwards +2

Focusing on three-pion states with maximal isospin (${\pi }^{+}{\pi }^{+}{\pi }^{+}$), we present the first non-perturbative determination of an energy-dependent three-hadron scattering amplitude from…
