Quantum chromodynamics on-lattice

This paper describes a new numerical QCD calculation method (direct minimization of QCD-QED-action) and its results for the first-generation (u,d) hadrons. Here we start with the standard color-Lagrangian LQCD=LDirac+Lgluon , model the quarks qi as parameterized gaussians, and the gluons Agi as Ritz-Galerkin-series. We minimize the Lagrangian numerically with parameters par=(par(q),{αk},par(Ag)) for first-generation hadrons (nucleons, pseudo-scalar mesons, vector mesons). The resulting parameters yield the correct masses, correct magnetic moments for the nucleons, the gluon-distribution and the quark-distribution with interesting insights into the hadron structure.

I present our recent results on the critical end point in the \mu_B-T phase diagram of QCD with two flavours of light dynamical quarks and compare them with similar results from other groups. Implications for a possible energy scan at the RHIC are discussed. I also comment briefly on the new results of great relevance to heavy ion collisions from finite temperature lattice QCD simulations on speed of sound, specific heat and on the fate of J/\psi.

I review a few selected topics in lattice quantum chromodynamics, focusing more on the recent results. These include (i) the equation of state and speed of sound, (ii) J/ψ suppression, (iii) flavour correlations and (iv) the QCD phase diagram in the µ-T plane.
Searching for new physics at the frontiers with lattice quantum chromodynamics
Annals of the New York Academy of Sciences, 2012
Numerical lattice-quantum chromodynamics (QCD) simulations, when combined with experimental measurements, allow the determination of fundamental parameters of the particle-physics Standard Model and enable searches for physics beyond-the-Standard Model. We present the current status of lattice-QCD weak matrix element calculations needed to obtain the elements and phase of the Cabibbo-Kobayashi-Maskawa (CKM) matrix and to test the Standard Model in the quark-flavor sector. We then discuss evidence that may hint at the presence of new physics beyond the Standard Model CKM framework. Finally, we discuss two opportunities where we expect lattice QCD to play a pivotal role in searching for, and possibly discovery of, new physics at upcoming high-intensity experiments: rare K → decays and the muon anomalous magnetic moment. The next several years may witness the discovery of new elementary particles at the Large Hadron Collider (LHC). The interplay between lattice QCD, high-energy experiments at the LHC, and high-intensity experiments will be needed to determine the underlying structure of whatever physics beyond-the-Standard Model is realized in nature.
Recent progress in lattice QCD

A brief overview of the status of lattice QCD is given, with emphasis on topics relevant to phenomenology. The calculation of the light quark spectrum, the lattice prediction of [alpha] [sub [ovr MS]] (M [sub Z]), and the calculation of f[sub B] are discussed. 3 figs., 3 tabs., 40 refs.

Recent developments in lattice QCD
Pramana, 1993
I review the current status of several lattice QCD results. I concentrate on new analytical developments and on numerical results relevant to phenomenology.
15th International Workshop on Deep-Inelastic Scattering and Related Subjects DIS 2007, 2007
In this short talk I will present some recent developments from lattice QCD. The presentation is prepared for non-experts with emphasis on general information which will hopefully act as a guide on how to assess phenomenological results presented from various lattice simulations.
