QCD Thermodynamics on the Lattice [PDF]
Advances in High Energy Physics, 2013 A remarkable progress has been made in the understanding of the hot and dense QCD matter using lattice gauge theory. The issues which are very well understood as well as those which require both conceptual and algorithmic advances are highlighted.

Nuclear Physics B - Proceedings Supplements, 1995 We show that the perturbatively-improved gluon action for QCD, once it is tadpole-improved, gives accurate results even with lattice spacings as large as 0.4~fm. {\em No\/} tuning of the couplings is required. Using this action and lattice spacing, we obtain a static potential that is rotationally invariant to within a few percent, the spin-averaged ...

Application of machine learning to the study of QCD transition in heavy ion collisions
He 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
He 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]
EPJ 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]
EPJ 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 ...

Neutral B -meson mixing from full lattice QCD at the physical point [PDF]
Physical Review D, 2019 We calculate the bag parameters for neutral $B$-meson mixing in and beyond the Standard Model, in full four-flavor lattice QCD for the first time. We work on gluon field configurations that include the effect of $u$, $d$, $s$, and $c$ sea quarks with the

Lattice QCD and Three-Particle Decays of Resonances [PDF]
Annual Review of Nuclear and Particle Science, 2019 Most strong-interaction resonances have decay channels involving three or more particles, including many of the recently discovered X, Y, and Z resonances.

Aspects of chiral transition in a Hadron Resonance Gas model [PDF]
EPJ Web of Conferences, 2022 We study the chiral condensate for 2 + 1 flavor QCD with physical quarks within a non-interacting Hadron Resonance Gas (HRG) model. By including the latest information on the mass variation of the hadrons concerning the light quark mass, from lattice QCD
