The energy-dependent $\pi^+ \pi^+ \pi^+$ scattering amplitude from QCD / Hansen, Maxwell T. (CERN ; U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Briceño, Raul A. (Jefferson Lab ; Old Dominion U.) ; Edwards, Robert G. (Jefferson Lab) ; Thomas, Christopher E. (Cambridge U., DAMTP) ; Wilson, David J. (Cambridge U., DAMTP) /Hadron Spectrum Collaboration
Focusing on three-pion states with maximal isospin (

π^{+} π^{+} π^{+}

$\pi^+\pi^+\pi^+$ ), we present the first non-perturbative determination of an energy-dependent three-hadron scattering amplitude from first-principles QCD. The calculation combines finite-volume three-hadron energies, extracted using numerical lattice QCD, with a relativistic finite-volume formalism, required to interpret the results. [...]

The role of boundary conditions in quantum computations of scattering observables / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Guerrero, Juan V. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Sturzu, Alexandru M. (New Coll. of Florida)
Quantum computing may offer the opportunity to simulate strongly-interacting field theories, such as quantum chromodynamics, with physical time evolution. This would give access to Minkowski-signature correlators, in contrast to the Euclidean calculations routinely performed at present. [...]

Consistency checks for two-body finite-volume matrix elements: II. Perturbative systems / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Jackura, Andrew W. (Jefferson Lab ; Old Dominion U.)
Using the general formalism presented in Refs. [1,2], we study the finite-volume effects for the

2 + J \to 2

$\mathbf{2}+\mathcal{J}\to\mathbf{2}$ matrix element of an external current coupled to a two-particle state of identical scalars with perturbative interactions. [...]

Long-range electroweak amplitudes of single hadrons from Euclidean finite-volume correlation functions / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U. (main)) ; Davoudi, Zohreh (Maryland U. ; Wako, RIKEN) ; Hansen, Maxwell T. (CERN) ; Schindler, Matthias R. (U. South Carolina, Columbia) ; Baroni, Alessandro (U. South Carolina, Columbia ; Los Alamos Natl. Lab., Theor. Div.)
A relation is presented between single-hadron long-range matrix elements defined in a finite Euclidean spacetime, and the corresponding infinite-volume Minkowski amplitudes. This relation is valid in the kinematic region where any number of two-hadron states can simultaneously go on shell, so that the effects of strongly-coupled intermediate channels are included. [...]

Consistency checks for two-body finite-volume matrix elements: Conserved currents and bound states / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Jackura, Andrew W. (Jefferson Lab ; Old Dominion U.)
Recently, a framework has been developed to study form factors of two-hadron states probed by an external current. The method is based on relating finite-volume matrix elements, computed using numerical lattice QCD, to the corresponding infinite-volume observables. [...]

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. [...]

Unitarity of the infinite-volume three-particle scattering amplitude arising from a finite-volume formalism / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Sharpe, Stephen R. (Washington U., Seattle) ; Szczepaniak, Adam P. (Indiana U., Bloomington (main) ; Indiana U., CEEM ; Jefferson Lab)
In a previous publication, two of us derived a relation between the scattering amplitude of three identical bosons,

M_{3}

$\mathcal M_3$ , and a real function referred to as the {divergence-free} K matrix and denoted

K_{df, 3}

$\mathcal K_{\text{df},3}$ . The result arose in the context of a relation between finite-volume energies and

K_{df, 3}

$\mathcal K_{\text{df},3}$ , derived to all orders in the perturbative expansion of a generic low-energy effective field theory. [...]

In this work we develop a Lorentz-covariant version of the previously derived formalism for relating finite-volume matrix elements to

Finite-volume matrix elements of two-body states / Baroni, Alessandro (South Carolina U.) ; Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Ortega-Gama, Felipe G. (Coll. William and Mary)
In this talk, we present a framework for studying structural information of resonances and bound states coupling to two-hadron scattering states. This makes use of a recently proposed finite-volume formalism to determine a class of observables that are experimentally inaccessible but can be accessed via lattice QCD. [...]
