Finite-volume formalism for at maximal isospin
Maxwell T. Hansen, Fernando Romero-López, Stephen R. Sharpe
We extend the relativistic field theoretic finite-volume formalism to scattering states at maximal isospin, . As in previous work using the relativistic field theory…
Comparison of integral equations used to study for a stable
Sebastian M. Dawid, Fernando Romero-López, Stephen R. Sharpe
We perform a detailed comparison between three formalisms used in recent studies of scattering, which aim to understand the properties of the doubly-charmed tetraquark, $T_{…
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…
