Lattice quantum chromodynamics: Some topics

Lattice Kaon Physics

I review lattice quantum chromodynamics as relevant to the kaon system. Topics covered include the pseudoscalar masses and decay constants, the chiral effective lagrangian, f K / f π , semi-leptonic kaon decay form factors, and the neutral kaon oscillation parameter B K. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

Recent developments in Quantum Chromodynamics (QCD) are reviewed on three major topics where nonper-turbative gluon excitations of the QCD vacuum and the physical properties of the confining flux play a central role: (1) New lattice results on the spectrum and wave functions of heavy QQgluon molecules, known as heavy hybrids, will be discussed. (2) Recent advances on the glueball spectrum in la...

Quantum chromodynamics with advanced computing

We survey results in lattice quantum chromodynamics from groups in the USQCD Collaboration. The main focus is on physics, but many aspects of the discussion are aimed at an audience of computational physicists.

Strong Coupling 1]N Expansion in the Gluonic Sector of Lattice Quantum Chromodynamics

The vacuum state of gluonic quantum chromodynamics on the lattice is determined up to fifth order in a 1IN c expansion ( N = number of colours). The vacuum expectation value of the gluon field squared Fa,vF~ ~ is deduced. The quark-antiquark and gluon-gluon potential is calculated in the same limit up to the 1/N~ order.
