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…
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…
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 .…
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…
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 .…
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…
