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

open access: yesEur 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.

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

open access: yesFrontiers 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 ...

Quantum simulation of lattice QCD with improved Hamiltonians [PDF]

open access: yesPhysical 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]

open access: yesPhysical 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]

open access: yesEPJ 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.

Leading hadronic contribution to the muon magnetic moment from lattice QCD [PDF]

open access: yesNature, 2020
The standard model of particle physics describes the vast majority of experiments and observations involving elementary particles. Any deviation from its predictions would be a sign of new, fundamental physics.

Progress in $x$-dependent partonic distributions from lattice QCD [PDF]

open access: yesProceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2021
We review the latest progress in lattice QCD calculations of the partonic structure of hadrons. This structure is, in particular, described in terms of G-dependent distributions, the simplest of which are the standard parton distribution functions (PDFs).

Skewness, kurtosis, and the fifth and sixth order cumulants of net baryon-number distributions from lattice QCD confront high-statistics STAR data [PDF]

open access: yesPhysical Review D, 2020
We present new results on up to sixth-order cumulants of net baryon-number fluctuations at small values of the baryon chemical potential, I¼B, obtained in lattice QCD calculations with physical values of light and strange quark masses.

QCD static force in gradient flow [PDF]

open access: yesEPJ Web of Conferences, 2022
We review our recent study on the QCD static force using gradient flow at next-to-leading order in the strong coupling. The QCD static force has the advantage of being free of the O(ΛQCD) renormalon appearing in the static potential but suffers from poor

Consistency of hadronic vacuum polarization between lattice QCD and the R ratio [PDF]

open access: yesPhysical Review D, 2020
There are emerging tensions for theory results of the hadronic vacuum polarization contribution to the muon anomalous magnetic moment both within recent lattice QCD calculations and between some lattice QCD calculations and R-ratio results. In this paper
