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.

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.

Communications in Mathematical Physics, 2013 We construct a mathematically well--defined framework for the kinematics of Hamiltonian QCD on an infinite lattice in $\R^3$, and it is done in a C*-algebraic context. This is based on the finite lattice model for Hamiltonian QCD developed by Kijowski, Rudolph e.a.. To extend this model to an infinite lattice, we need to take an infinite tensor product

String breaking in lattice QCD [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 The separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or string, which should break in the presence of light quark-antiquark pairs. This expected zero temperature phenomenon has proven elusive in simulations of lattice QCD.

Analytical relation between quark confinement and chiral symmetry breaking in odd-number lattice QCD
EPJ Web of Conferences, 2014 To clarify the relation between confinement and chiral symmetry breaking in QCD, we consider a temporally odd-number lattice, with the temporal lattice size Nt being odd.

Hadronic vacuum polarization contribution to the muon g−2 with ( 2+1 )-flavor lattice QCD on a larger than (10 fm)4 lattice at the physical point [PDF]
Physical Review D, 2019 We study systematic uncertainties in the lattice QCD computation of hadronic vacuum polarization (HVP) contribution to the muon $g-2$. In this article we investigate three systematic effects; finite volume (FV) effect, cutoff effect, and integration ...

Progress of Theoretical Physics Supplement, 2007 We review lattice results that probe properties of high temperature QCD at different length scales and can help to elucidate its non-perturbative structure. We examine the flavor and chemical potential dependence of electric and magnetic screening lengths as well as the QCD equation of state.

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 ...

First direct lattice-QCD calculation of the x -dependence of the pion parton distribution function [PDF]
Physical Review D, 2018 We present the first direct lattice-QCD calculation of the Bjorken-$x$ dependence of the valence quark distribution in the pion. Using large-momentum effective theory (LaMET), we calculate the boosted pion state with long Wilson link operators.
