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…

Finite-volume formalism for $N π π$ at maximal isospin

Maxwell T. Hansen, Fernando Romero-López, Stephen R. Sharpe

We extend the relativistic field theoretic finite-volume formalism to $N π π$ scattering states at maximal isospin, $I = 5/2$ . As in previous work using the relativistic field theory…

Implementing the finite-volume three-pion scattering formalism across all non-maximal isospins

Athari Alotaibi, Maxwell T. Hansen, Raúl A. Briceño

We present a numerical exploration of the relativistic-field-theory (RFT) formalism for three pions with all possible values of non-maximal isospin, $I_{π π π} = 2$ , $1$ and $0$ . Usi…
