Electrical conductivity of the quark-gluon plasma: perspective from lattice QCD [PDF]
European Physical Journal A, 2020 A discussion on the electrical conductivity of the quark-gluon plasma as determined by lattice QCD is given. After a reminder of basic definitions and expectations, various methods for spectral reconstruction are reviewed, including the use of Ansätze ...

Three-body unitarity versus finite-volume π+π+π+ spectrum from lattice QCD [PDF]
Physical Review D, 2019 Strong three-body interactions above threshold govern the dynamics of many exotics and conventional excited mesons and baryons. Three-body finite-volume energies calculated from lattice QCD promise an ab-initio understanding of these systems.

Lattice QCD in Rotating Frames [PDF]
Physical Review Letters, 2013 We formulate lattice QCD in rotating frames to study the physics of QCD matter under rotation. We construct the lattice QCD action with the rotational metric and apply it to the Monte Carlo simulation. As the first application, we calculate the angular momenta of gluons and quarks in the rotating QCD vacuum.

Strangeness $S=-1$ hyperon-nucleon interactions: chiral effective field theory vs. lattice QCD
, 2018 Hyperon-nucleon interactions serve as basic inputs to studies of hypernuclear physics and dense (neutron) stars. Unfortunately, a precise understanding of these important quantities have lagged far behind that of the nucleon-nucleon interaction due to ...

Chiral Fermions Algorithms In Lattice QCD
East European Journal of Physics, 2019 The theory that explains the strong interactions of the elementary particles, as part of the standard model, it is the so-called Quantum Chromodynamics (QCD) theory.

Master integrals for two-loop QCD corrections to quark quasi PDFs
Journal of High Energy Physics, 2020 We compute the master integrals for the two-loop QCD corrections to quark quasi parton distribution functions (PDFs) in the large momentum effective theory (LaMET). With a proper canonical basis, we derive the analytical results for the three families of

QCD Level Density from Maximum Entropy Method
, 2005 We propose a method to calculate the QCD level density directly from the thermodynamic quantities obtained by lattice QCD simulations with the use of the maximum entropy method (MEM).

Twisted mass Lattice QCD [PDF]
, 2004 I review the main theoretical properties and some recent analytical and numerical investigations of the formulations of lattice QCD with chirally twisted Wilson quarks (also known as twisted mass lattice QCD).Comment: Lattice 04 (plenary), 7 pages ...

The γπ → ππ anomaly from lattice QCD and dispersion relations
Journal of High Energy Physics, 2021 We propose a formalism to extract the γπ → ππ chiral anomaly F 3π from calculations in lattice QCD performed at larger-than-physical pion masses. To this end, we start from a dispersive representation of the γ (*) π → ππ amplitude, whose main quark-mass ...
