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.

QCD static force in gradient flow [PDF]
EPJ 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
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 ...

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.

On the role of isospin violation in the pion–nucleon σ-term
Physics Letters B, 2023 In recent years, a persistent tension between phenomenological and lattice QCD determinations of the pion–nucleon σ-term σπN has developed. In particular, lattice-QCD calculations have matured to the point that isospin-violating effects need to be ...

Excited bottomonia in quark-gluon plasma from lattice QCD
Physics Letters B, 2020 We present the first lattice QCD study of up to 3S and 2P bottomonia at non-zero temperatures. Correlation functions of bottomonia were computed using novel bottomonium operators and a variational technique, within the lattice non-relativistic QCD ...

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
