Two- and three-meson scattering amplitudes with physical quark masses from lattice QCD
Sebastian M. Dawid, Zachary T. Draper, Andrew D. Hanlon +5
We study systems of two and three mesons composed of pions and kaons at maximal isospin using four CLS ensembles with fm, including one with approximately physica…
QCD predictions for physical multimeson scattering amplitudes
Sebastian M. Dawid, Zachary T. Draper, Andrew D. Hanlon +5
We use lattice QCD calculations of the finite-volume spectra of systems of two and three mesons to determine, for the first time, three-particle scattering amplitudes with physical…
Three relativistic neutrons in a finite volume
Zachary T. Draper, Maxwell T. Hansen, Fernando Romero-López +1
We generalize the relativistic field-theoretic (RFT) three-particle finite-volume formalism to systems of three identical, massive, spin- fermions, such as three neutrons. Thi…
Interactions of , and systems at maximal isospin from lattice QCD
Zachary T. Draper, Andrew D. Hanlon, Ben Hörz +3
We study the interactions of systems of two and three nondegenerate mesons composed of pions and kaons at maximal isospin using lattice QCD, specifically , and…
scattering in partially-quenched twisted-mass chiral perturbation theory
Zachary T. Draper, Stephen R. Sharpe
We study pion-pion scattering in partially-quenched twisted-mass lattice QCD using chiral perturbation theory. The specific partially-quenched setup corresponds to that used in num…
Applicability of the two-particle quantization condition to partially-quenched theories
Zachary T. Draper, Stephen R. Sharpe
Partial quenching allows one to consider correlation functions and amplitudes that do not arise in the corresponding unquenched theory. For example, physical -wave pion scatteri…
