Microscopic clustering in light nuclei

M Freer, H Horiuchi, Y Kanada-En'yo, D Lee… - Reviews of Modern …, 2018 - APS
This review examines the tendency of light nuclei to exhibit clustering, where correlations
between nucleons result in the formation of precipitates, typically α particles. The …

QCD and strongly coupled gauge theories: challenges and perspectives

N Brambilla, S Eidelman, P Foka, S Gardner… - The European Physical …, 2014 - Springer
We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

Novel quark smearing for hadrons with high momenta in lattice QCD

GS Bali, B Lang, BU Musch, A Schäfer… - Physical Review D, 2016 - APS
Hadrons in lattice QCD are usually created employing smeared interpolators. We introduce
a new quark smearing that allows us to maintain small statistical errors and good overlaps of …

Novel quark-field creation operator construction for hadronic physics in lattice QCD

M Peardon, J Bulava, J Foley, C Morningstar… - Physical Review D …, 2009 - APS
A new quark-field smearing algorithm is defined which enables efficient calculations of a
broad range of hadron correlation functions. The technique applies a low-rank operator to …

Toward the excited meson spectrum of dynamical QCD

JJ Dudek, RG Edwards, MJ Peardon, DG Richards… - Physical Review D …, 2010 - APS
We present a detailed description of the extraction of the highly excited isovector meson
spectrum on dynamical anisotropic lattices using a new quark-field construction algorithm …

Light hadron masses from lattice QCD

Z Fodor, C Hoelbling - Reviews of Modern Physics, 2012 - APS
This article reviews lattice QCD results for the light hadron spectrum. An overview of different
formulations of lattice QCD with discussions on the fermion doubling problem and …

Flavor blindness and patterns of flavor symmetry breaking in lattice simulations<? format?> of up, down, and strange quarks

W Bietenholz, V Bornyakov, M Göckeler, R Horsley… - Physical Review D …, 2011 - APS
QCD lattice simulations with 2+ 1 flavors (when two quark flavors are mass degenerate)
typically start at rather large up-down and strange quark masses and extrapolate first the …

Parton distribution functions from Ioffe time pseudodistributions from lattice calculations: approaching the physical point

B Joó, J Karpie, K Orginos, AV Radyushkin… - Physical Review Letters, 2020 - APS
We present results for the unpolarized parton distribution function of the nucleon computed
in lattice QCD at the physical pion mass. This is the first study of its kind employing the …
