On the equivalence of left-hand-cut and three-body formalisms
André Baião-Raposo, Raul Briceño, Sebastian M. Dawid
The "left-hand cut problem" in lattice QCD arises when exchange singularities invalidate standard relations used to extract scattering amplitudes from the finite-volume spectrum. I…
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, 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…
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…
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…
Coulomb confinement in the Hamiltonian limit
Sebastian M. Dawid, Wyatt A. Smith, Arkaitz Rodas +4
The Gribov--Zwanziger scenario attributes the phenomenon of confinement to the instantaneous interaction term in the QCD Hamiltonian in the Coulomb gauge. For a static quark-antiqu…
Analytic continuation of the finite-volume three-particle amplitudes
Sebastian M. Dawid
One has to study multivariable scattering amplitudes to extract properties of the three-body states from the generalizations of the Lüscher finite-volume formalism. In particular,…
Infinite volume, three-body scattering formalisms in the presence of bound states
Sebastian M. Dawid
Strong interactions produce a rich spectrum of resonances that decay into three or more hadrons. Understanding their phenomenology requires a theoretical framework to extract param…
Solving relativistic three-body integral equations in the presence of bound states
Andrew W. Jackura, Raúl A. Briceño, Sebastian M. Dawid +2
We present a systematically improvable method for numerically solving relativistic three-body integral equations for the partial-wave projected amplitudes. The method consists of a…
The Coulomb flux tube revisited
Sebastian M. Dawid, Adam P. Szczepaniak
We perform Yang-Mills lattice simulation of the electric field distribution in the Coulomb gauge for different values of to further investigate the nature of the Coulom…
