Scattering amplitudes from quantum hardware a la RESOs
Raul A Briceno, Ivan M Burbano, Anthony N Ciavarella +3
We report the first quantum-hardware implementation of Real-time Estimators for Scattering Observables (RESOs). The physical model is a one-dimensional lattice theory of non-relati…
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…
Analytic decomposition of two-body electroweak processes with left-hand cuts
André Baião-Raposo, Raúl A. Briceño, Nicolas Lang +2
We derive an on-shell representation for electroweak transition amplitudes involving two hadrons in both the initial and final state for systems where there are left-hand…
Isotensor scattering with a resonant subsystem from QCD
Raúl A. Briceño, Maxwell T. Hansen, Andrew W. Jackura +2
This work presents a lattice quantum chromodynamics (QCD) determination of scattering amplitudes for the isospin-2 channel with angular momentum and parity . The…
Implementing the finite-volume three-pion scattering formalism across all non-maximal isospins
Athari Alotaibi, Maxwell T. Hansen, Raúl A. Briceño
We present a numerical exploration of the relativistic-field-theory (RFT) formalism for three pions with all possible values of non-maximal isospin, , and . Usi…
Symmetrizing relativistic three-body partial wave amplitudes
Andrew W. Jackura, Nicholas C. Chambers, Raúl A. Briceño
S matrix principles and symmetries impose constraints on three-particle scattering amplitudes, which can be formulated as a class of integral equations for their partial wave proje…
Real-time Estimators for Scattering Observables: A full account of finite volume errors for quantum simulation
Ivan M. Burbano, Marco A. Carrillo, Rana Urek +2
The real-time correlators of quantum field theories can be directly probed through new approaches to simulation, such as quantum computing and tensor networks. This provides a new…
Simulating lattice fermion doubling with a Floquet drive
Raúl A. Briceño, William Gyory, Thomas Iadecola +1
We consider a recently discovered mathematical correspondence between the spectra of a naively discretized lattice fermion and that of a periodically driven (i.e., Floquet) quantum…
Signs of Non-Monotonic Finite-Volume Corrections to
Zack B. Hall, Dimitra A. Pefkou, Aaron S. Meyer +10
We study finite-volume (FV) corrections to determinations of via lattice quantum chromodynamics (QCD) using analytic results and numerical analysis. We observe that H…
Extracting scattering amplitudes for arbitrary two-particle systems with one-particle left-hand cuts via lattice QCD
André Baião Raposo, Raúl A Briceño, Maxwell T Hansen +1
We derive a general formalism that relates the spectrum of two-particle systems in a finite volume to physical scattering amplitudes, taking into account the presence of any left-h…
Partial-wave projection of relativistic three-body amplitudes
Raúl A. Briceño, Caroline S. R. Costa, Andrew W. Jackura
We derive the integral equations for partial-wave projected three-body scattering amplitudes, starting from the integral equations for three-body amplitudes developed for lattice Q…
Electroweak three-body decays in the presence of two- and three-body bound states
Raul A. Briceño, Andrew Jackura, Dimitra A. Pefkou +1
Recently, formalism has been derived for studying electroweak transition amplitudes for three-body systems both in infinite and finite volumes. The formalism provides exact relatio…
Partial-wave projection of the one-particle exchange in three-body scattering amplitudes
Andrew W. Jackura, Raúl A. Briceño
As the study of three-hadron physics from lattice QCD matures, it is necessary to develop proper analysis tools in order to reliably study a variety of phenomena, including resonan…
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…
Two-current transition amplitudes with two-body final states
Keegan H. Sherman, Felipe G. Ortega-Gama, Raúl A. Briceño +1
We derive the on-shell form of amplitudes containing two external currents with a single hadron in the initial state and two hadrons in the final state, denoted as $1+\mathcal{J}\t…
