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-particle formalism for multiple channels: the system in isosymmetric QCD
Zachary T. Draper, Stephen R. Sharpe
We generalize previous three-particle finite-volume formalisms to allow for multiple three-particle channels. For definiteness, we focus on the two-channel and $K \overlin…
