Three-body study of the from lattice QCD
Herzallah Alharazin, André Baião Raposo, John Bulava +7
We discuss an ongoing first lattice study of the doubly-charmed tetraquark (3875) via a three-body approach. We investigate the system in the , sector,…
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…
Finite- and infinite-volume study of scattering
Sebastian M. Dawid, Fernando Romero-López, Stephen R. Sharpe
We develop a comprehensive framework for extracting the pole position and properties of the doubly-charmed tetraquark from lattice QCD data using the relativis…
Finite-volume quantization condition from the representation
Sebastian M. Dawid, Andrew W. Jackura, Adam P. Szczepaniak
We propose a new model-independent method for determining hadronic resonances from lattice QCD. The formalism is derived from the general principles of unitarity and analyticity, a…
