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…
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-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,…
Evolution of Efimov States
Sebastian M. Dawid, Md Habib E Islam, Raúl A. Briceño +1
The Efimov phenomenon manifests itself as an emergent discrete scaling symmetry in the quantum three-body problem. In the unitarity limit, it leads to an infinite tower of three-bo…
Analytic continuation of the relativistic three-particle scattering amplitudes
Sebastian M. Dawid, Md Habib E Islam, Raúl A. Briceño
We investigate the relativistic scattering of three identical scalar bosons interacting via pair-wise interactions. Extending techniques from the non-relativistic three-body scatte…
Snowmass white paper: Need for amplitude analysis in the discovery of new hadrons
Miguel Albaladejo, Marco Battaglieri, Lukasz Bibrzycki +22
We highlight the need for the development of comprehensive amplitude analysis methods to further our understanding of hadron spectroscopy. Reaction amplitudes constrained by first…
Novel approaches in Hadron Spectroscopy
JPAC Collaboration, Miguel Albaladejo, Lukasz Bibrzycki +15
The last two decades have witnessed the discovery of a myriad of new and unexpected hadrons. The future holds more surprises for us, thanks to new-generation experiments. Understan…
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…
Bound states in the B-matrix formalism for the three-body scattering
Sebastian M. Dawid, Adam P. Szczepaniak
We consider a model of relativistic three-body scattering with a bound state in the two-body sub-channel. We show that the naïve K-matrix type parametrization, here referred to as…
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…
On the Equivalence of Three-Particle Scattering Formalisms
A. W. Jackura, S. M. Dawid, C. Fernández-Ramírez +5
In recent years, different on-shell scattering formalisms have been proposed to be applied to both lattice QCD and infinite volume scattering processes. W…
Renormalization group procedure for potential
Sebastian M. Dawid, Rafał Gonsior, Jan Kwapisz +3
Schrödinger equation with potential exhibits a limit cycle, described in the literature in a broad range of contexts using various regularizations of the singularity at $r…
