Update on ɛK with lattice QCD inputs

open access: yesEPJ 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 with Ginsparg-Wilson fermions [PDF]

open access: green, 1999
Lattice QCD using fermions whose Dirac operator obeys the Ginsparg-Wilson relation, is perhaps the best known formulation of QCD with a finite cutoff. It reproduces all the low energy QCD phenomenology associated with chiral symmetry at finite lattice ...

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

open access: yesEPJ 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.

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.

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

Application of machine learning to the study of QCD transition in heavy ion collisions

open access: yesHe jishu, 2023
In high-energy heavy ion collisions, quarks and gluons are released from the colliding nucleus to form a new state of nuclear matter called deconfined quark gluon plasma (QGP). To study the transition from normal nuclear matter or hadron resonance gas to

Progress on QCD properties in strong magnetic fields from lattice QCD

open access: yesHe jishu, 2023
We review the current status of quantum chromodynamics (QCD) properties in strong magnetic fields from lattice QCD. After a general introduction, we briefly present the implementation of a background magnetic field onto a lattice and discuss the recent ...

Lattice Study of QCD Properties at the “Govorun” Supercomputer [PDF]

open access: yesEPJ Web of Conferences, 2020
This report is devoted to Lattice QCD simulations carried out at the “Govorun” supercomputer. The basics of Lattice QCD methodology, the main Lattice QCD algorithms and the most numerically demanding routines are reviewed.

Thermal Transitions in Dense Two-Colour QCD [PDF]

open access: yesEPJ Web of Conferences, 2022
The infamous sign problem makes it impossible to probe dense (baryon density μB > 0) QCD at temperatures near or below the deconfinement threshold. As a workaround, one can explore QCD-like theories such as twocolour QCD (QC2D) which don’t suffer from ...

The negative-parity spin-1/2 Λ baryon spectrum from lattice QCD and effective theory

open access: yesPhysics 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.
