Machine Learning Neutrino-Nucleus Cross Sections II: More Leptons

Daniel C. Hackett, Joshua Isaacson, Shirley Weishi Li +2

Neutrino-nucleus cross sections are essential inputs for long-baseline neutrino oscillation experiments, yet remain challenging to model with high precision. Recent work demonstrat…

Drell-Yan lepton pair production from low to high transverse momentum

Benoît Assi, Enrico Bothmann, John Campbell +7

We present a technique for computing Drell-Yan lepton pair production at particle-level that achieves NLO and approximate NLL accuracy at small to moderate transverse mo…

First constraints on the nonperturbative gluon Collins-Soper kernel

Artur Avkhadiev, Yang Fu, Phiala E. Shanahan +2

The gluon Collins-Soper kernel, which encodes the rapidity evolution of transverse-momentum-dependent gluon distributions, is constrained for the first time in the nonperturbative…

Direct calculation of parton distributions in momentum space from lattice QCD

Anthony V. Grebe, Daniel C. Hackett, Michael L. Wagman +2

Coulomb-gauge quasi-parton distributions can be computed directly in momentum space on a finite lattice, enabled by the commutativity of their renormalization and Fourier transform…

Excited-state uncertainties in lattice-QCD calculations of hadron masses and scattering phase shifts

William Detmold, Anthony V. Grebe, Daniel C. Hackett +4

Lattice QCD has historically produced energy results interpretable as either estimates relying on implicit assumptions about asymptotic behavior or one-sided upper bounds. New Lanc…

Excited-state uncertainties in lattice-QCD calculations of multi-hadron systems

William Detmold, Anthony V. Grebe, Daniel C. Hackett +4

Excited-state effects lead to hard-to-quantify systematic uncertainties in lattice quantum chromodynamics (LQCD) spectroscopy calculations when computationally accessible imaginary…

An extraction of the Collins-Soper kernel from a joint analysis of experimental and lattice data

Artur Avkhadiev, Valerio Bertone, Chiara Bissolotti +6

We present a first joint extraction of the Collins-Soper kernel (CSK) combining experimental and lattice QCD data in the context of an analysis of transverse-momentum-dependent dis…

Filtered Rayleigh-Ritz is all you need

Ryan Abbott, Daniel C. Hackett, George T. Fleming +2

Recent work has shown that the (block) Lanczos algorithm can be used to extract approximate energy spectra and matrix elements from (matrices of) correlation functions in quantum f…

Quantum fluctuations of quarks and gluons in nuclei

Michael L. Wagman

Acceptance talk for the 2024 Kenneth G. Wilson Award for Excellence in Lattice Field Theory: For key contributions to lattice QCD studies of noise reduction in nuclear systems, the…

Kinematically-enhanced interpolating operators for boosted hadrons

Rui Zhang, Anthony V. Grebe, Daniel C. Hackett +2

We propose to use interpolating operators for lattice quantum chromodyanmics (QCD) calculations of highly-boosted pions and nucleons with kinematically-enhanced ground-state overla…

Machine Learning Neutrino-Nucleus Cross Sections

Daniel C. Hackett, Joshua Isaacson, Shirley Weishi Li +2

Neutrino-nucleus scattering cross sections are critical theoretical inputs for long-baseline neutrino oscillation experiments. However, robust modeling of these cross sections rema…

Lanczos, the transfer matrix, and the signal-to-noise problem

Michael L. Wagman

This work introduces a method for determining the energy spectrum of lattice quantum chromodynamics (LQCD) by applying the Lanczos algorithm to the transfer matrix and using a boot…
