Lattice QCD and neutrino-nucleus scattering [PDF]
European Physical Journal A, 2019 This document is one of a series of white papers from the USQCD Collaboration. Here, we discuss opportunities for Lattice QCD in neutrino-oscillation physics, which inevitably entails nucleon and nuclear structure.

Constraints on charm-anticharm asymmetry in the nucleon from lattice QCD [PDF]
, 2020 We present the first lattice QCD calculation of the charm quark contribution to the nucleon electromagnetic form factors $G^c_{E,M}(Q^2)$ in the momentum transfer range $0\leq Q^2 \leq 1.4$ $\rm GeV^2$.

The hadronic vacuum polarization contribution to the muon g − 2 from lattice QCD [PDF]
Journal of High Energy Physics, 2017 We present a calculation of the hadronic vacuum polarization contribution to the muon anomalous magnetic moment, aμhvp, in lattice QCD employing dynamical up and down quarks. We focus on controlling the infrared regime of the vacuum polarization function.

Small bits of cold dense matter
Physics Letters B, 2018 The behavior of QCD at high baryon density and low temperature is crucial to understanding the properties of neutron stars and gravitational waves emitted during their mergers.

Fixed Scale Approach to Equation of State in Lattice QCD [PDF]
, 2009 A new approach to study the equation of state in finite-temperature QCD is proposed on the lattice. Unlike the conventional method in which the temporal lattice size $N_t$ is fixed, the temperature $T$ is varied by changing $N_t$ at fixed lattice scale ...

Exploring Partonic Structure of Hadrons Using ab initio Lattice QCD Calculations. [PDF]
Physical Review Letters, 2017 Following our previous proposal, we construct a class of good "lattice cross sections" (LCSs), from which we can study the partonic structure of hadrons from ab initio lattice QCD calculations. These good LCSs, on the one hand, can be calculated directly

Datagrids for lattice QCD [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006 Abstract As the need for computing resources to carry out numerical simulations of Quantum Chromodynamics (QCD) formulated on a lattice has increased significantly, efficient use of the generated data has become a major concern. To improve on this, groups plan to share their configurations on a worldwide level within the International Lattice ...

Analytical relation between quark confinement and chiral symmetry breaking in odd-number lattice QCD
EPJ Web of Conferences, 2014 To clarify the relation between confinement and chiral symmetry breaking in QCD, we consider a temporally odd-number lattice, with the temporal lattice size Nt being odd.

Constituent-quark model description of triply heavy-baryon nonperturbative lattice QCD data [PDF]
, 2015 This paper provides results for the spectra of triply charmed and bottom baryons based on a constituent quark model approach. We take advantage of the assumption that potential models are expected to describe triply heavy baryons to a similar degree of ...
