The Causal Bootstrap: Bounding Smeared Spectral Functions from Non-Perturbative Euclidean Data

Ryan Abbott, Sarah Fields, William I. Jay +2

This work introduces the causal bootstrap, a framework for bounding smeared spectral observables from finite non-perturbative Euclidean data. The method optimizes over the convex s…

Moment Problems and Spectral Functions

Ryan Abbott, William Jay, Patrick Oare

Nevanlinna-Pick interpolation and moment problems use the analytic structures provided by causality in order to provide rigorous bounds on smeared spectral functions. This proceedi…

Moment problems and bounds for matrix-valued smeared spectral functions

Ryan Abbott, William I. Jay, Patrick R. Oare

Numerical analytic continuation arises frequently in lattice field theory, particularly in spectroscopy problems. This work shows the equivalence of common spectroscopic problems t…

Long-Distance Nuclear Matrix Elements for Neutrinoless Double-Beta Decay from Lattice QCD

Zohreh Davoudi, William Detmold, Zhenghao Fu +6

Neutrinoless double-beta () decay is a heretofore unobserved process which, if observed, would imply that neutrinos are Majorana particles. Interpretations of the stringent e…

Gravitational form factors of the pion from lattice QCD

Daniel C. Hackett, Patrick R. Oare, Dimitra A. Pefkou +1

The two gravitational form factors of the pion, and , are computed as functions of the momentum transfer squared in the kinematic region $0\leq -t< 2~\text{GeV…

Hadronic Structure, Conformal Maps, and Analytic Continuation

Thomas Bergamaschi, William I. Jay, Patrick R. Oare

We present a method for analytic continuation of retarded Green functions, including Euclidean Green functions computed using lattice QCD. The method is based on conformal maps and…

Neutrinoless Double Beta Decay from Lattice QCD: The Short-Distance Amplitude

William Detmold, William I. Jay, David J. Murphy +2

This work presents a determination of potential short-distance contributions to the unphysical decay through lattice QCD calculations. The hadronic cont…

Lattice QCD constraints on the parton distribution functions of

William Detmold, Marc Illa, David J. Murphy +5

The fraction of the longitudinal momentum of that is carried by the isovector combination of and quarks is determined using lattice QCD for the first time.…

Video from Stills: Lensless Imaging with Rolling Shutter

Nick Antipa, Patrick Oare, Emrah Bostan +2

Because image sensor chips have a finite bandwidth with which to read out pixels, recording video typically requires a trade-off between frame rate and pixel count. Compressed sens…
