Numerical exploration of three relativistic particles in a finite volume including two-particle resonances and bound states / Romero-López, Fernando (Valencia U., IFIC) ; Sharpe, Stephen R. (Washington U., Seattle) ; Blanton, Tyler D. (Washington U., Seattle) ; Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN)
In this work, we use an extension of the quantization condition, given in Ref. [1], to numerically explore the finite-volume spectrum of three relativistic particles, in the case that two-particle subsets are either resonant or bound. [...]

Analytic expansions of two- and three-particle excited-state energies / Grabowska, Dorota Maria (CERN) ; Hansen, Maxwell T. (U. Edinburgh, Higgs Ctr. Theor. Phys.)
The last years have seen significant developments in methods relating two- and three-particle finite-volume energies to scattering observables. These relations hold for both weakly and strongly interacting systems, and studying their predictions in limiting cases can provide important cross checks as well as giving useful insights into the general formulae. [...]

Analytic expansions of multi-hadron finite-volume energies. I. Two-particle states / Grabowska, Dorota M. (CERN) ; Hansen, Maxwell T. (U. Edinburgh (main))
We derive analytic expansions for the finite-volume energies of weakly-interacting two-particle systems, using the general relations between scattering amplitudes and energies derived by Lüscher and others. The relations hold for ground and excited states with both zero and non-zero total momentum in the finite-volume frame. [...]

Lattice QCD and Three-particle Decays of Resonances / Hansen, Maxwell T. (CERN) ; Sharpe, Stephen R. (Washington U., Seattle)
Most strong-interaction resonances have decay channels involving three or more particles, including many of the recently discovered $X$, $Y$ and $Z$ resonances. In order to study such resonances from first principles using lattice QCD, one must understand finite-volume effects for three particles in the cubic box used in calculations. [...]

Generalizing the relativistic quantization condition to include all three-pion isospin channels / Hansen, Maxwell T. (CERN) ; Romero-López, Fernando (Valencia U., IFIC) ; Sharpe, Stephen R. (U. Washington, Seattle (main))
We present a generalization of the relativistic, finite-volume, three-particle quantization condition for non-identical pions in isosymmetric QCD. The resulting formalism allows one to use discrete finite-volume energies, determined using lattice QCD, to constrain scattering amplitudes for all possible values of two- and three-pion isospin. [...]

Numerical study of the relativistic three-body quantization condition in the isotropic approximation / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Sharpe, Stephen R. (Washington U., Seattle)
We present numerical results showing how our recently proposed relativistic three-particle quantization condition can be used in practice. Using the isotropic (generalized $s$-wave) approximation, and keeping only the leading terms in the effective range expansion, we show how the quantization condition can be solved numerically in a straightforward manner.

Three-particle systems with resonant subprocesses in a finite volume / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Sharpe, Stephen R. (Washington U., Seattle)
In previous work, we have developed a relativistic, model-independent three-particle quantization condition, but only under the assumption that no poles are present in the two-particle K matrices that appear as scattering subprocesses. Here we lift this restriction, by deriving the quantization condition for identical scalar particles with a G-parity symmetry, in the case that the two-particle K matrix has a pole in the kinematic regime of interest. [...]
