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…
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…
