Isotensor $π π π$ scattering with a $ρ$ resonant subsystem from QCD

Raúl A. Briceño, Maxwell T. Hansen, Andrew W. Jackura +2

This work presents a lattice quantum chromodynamics (QCD) determination of $π π π$ scattering amplitudes for the isospin-2 channel with angular momentum and parity $J^{P} = 1^{+}$ . The…

$η$ and $η^{'}$ production in $J / ψ$ radiative decays from quantum chromodynamics

Mischa Batelaan, Jozef J. Dudek, Robert G. Edwards

We present a first principles calculation within quantum chromodynamics (QCD) of the radiative decays of the $J / ψ$ into the light pseudoscalar mesons $η$ and $η^{'}$ . Within a lattice…

$η$ and $η^{'}$ meson production in $J / ψ$ radiative decays from lattice QCD

Mischa Batelaan, Jozef J. Dudek, Robert G. Edwards

We report on the computation of amplitudes describing the radiative decay processes $J / ψ \to γ η$ and $J / ψ \to γ η^{'}$ from first principles via lattice QCD. Using lattices with tw…
