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_{…

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 theor…

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…
