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 ...

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).

Vacuum correlators at short distances from lattice QCD
Journal of High Energy Physics, 2021 Non-perturbatively computing the hadronic vacuum polarization at large photon virtualities and making contact with perturbation theory enables a precision determination of the electromagnetic coupling at the Z pole, which enters global electroweak fits ...

QCD on anisotropic lattices [PDF]
Nuclear Physics B, 1988 Abstract We study the formulation of QCD on anisotropic lattices with different couplings in space and time directions of a four-dimensional hypercube. A non-perturbative determination of the ratio of lattice spacings, ξ = aσ/aτ, as well as the ratio of Λ-parameters has been performed in the scaling regime of SU(3) gauge theory.

Nucl.Phys.Proc.Suppl. 47 (1996) 3-16, 1995 This is the Lattice '95 review of recent progress towards accurate QCD simulations using very coarse lattices. This development could have revolutionary implications for low energy (nonperturbative) QCD.

The negative-parity spin-1/2 Λ baryon spectrum from lattice QCD and effective theory
Physics Letters B, 2021 The spectrum of the negative-parity spin-1/2 Λ baryons is studied using lattice QCD and hadronic effective theory in a unitarized coupled-channel framework.

EPJ Web of ConferencesI review recent progress in lattice QCD calculations of the QCD phase diagram and equation of state at non-zero temperature and baryochemical potential. I also discuss some connections with heavy ion collisions.
