The x-dependence of hadronic parton distributions: A review on the progress of lattice QCD. [PDF]

Eur Phys J A Hadron Nucl, 2021
In this article, we review recent lattice calculations on the x-dependence of parton distributions, with the latter providing information on hadron structure.

Update on ɛK with lattice QCD inputs

EPJ Web of Conferences, 2018
We report updated results for ɛK, the indirect CP violation parameter in neutral kaons, which is evaluated directly from the standard model with lattice QCD inputs. We use lattice QCD inputs to fix B⌢K,Vcb,ξ0,ξ2,Vus, and mc(mc).

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method [PDF]

Frontiers in Physics, 2020
In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...

Lattice QCD Application Development within the US DOE Exascale Computing Project [PDF]

EPJ Web of Conferences, 2018
In October, 2016, the US Department of Energy launched the Exascale Computing Project, which aims to deploy exascale computing resources for science and engineering in the early 2020’s.

Opportunities for lattice QCD in quark and lepton flavor physics

European Physical Journal A, 2019
This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice QCD in quark and lepton flavor physics.

Gravitational Form Factors of the Proton from Lattice QCD. [PDF]

Physical Review Letters, 2023
The gravitational form factors (GFFs) of a hadron encode fundamental aspects of its structure, including its shape and size as defined from, e.g., its energy density.

Quantum simulation of lattice QCD with improved Hamiltonians [PDF]

Physical Review D, 2023
Quantum simulations of lattice gauge theories are anticipated to directly probe the real time dynamics of QCD, but scale unfavorably with the required truncation of the gauge fields.

Lattice QCD Equation of State at Finite Chemical Potential from an Alternative Expansion Scheme. [PDF]

Physical Review Letters, 2021
In this Letter, we introduce a novel scheme for extrapolating the equation of state of QCD to finite chemical potential that features considerably improved convergence properties and allows us to extend its reach to unprecedentedly high baryonic chemical

QCD confronts heavy-flavor and exotic hadrons [PDF]

EPJ Web of Conferences, 2022
A review of QCD-based theory approaches to study the heavy-flavor and exotic hadrons is given. The focus is on the results from lattice QCD and from lattice QCD complemented by effective field theories.
