Di-nucleons do not form bound states at heavy pion mass
John Bulava, M. A. Clark, Arjun S. Gambhir +16
We perform a high-statistics lattice QCD calculation of the low-energy two-nucleon scattering amplitudes. In order to address discrepancies in the literature, the calculation is pe…
Bayesian Analysis and Analytic Continuation of Scattering Amplitudes from Lattice QCD
Miguel Salg, Fernando Romero-López, William I. Jay
We present a novel procedure for analyzing the lattice-QCD spectrum via the finite-volume formalism to obtain constraints on multi-hadron scattering amplitudes at both real and com…
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_{…
The scattering amplitude at large
Jorge Baeza-Ballesteros, Pilar Hernández, Fernando Romero-López
We study the scaling of meson-meson scattering amplitudes with the number of colors, . We use lattice calculations in a theory with degenerate flavors, w…
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…
