Integrability of Quantum Chromodynamics in 1+1 dimensions has recently been suggested by formulating it as a perturbed conformal Wess-Zumino-Witten theory. The present paper further elucidates this formulation, by presenting a detailed BRST analysis. CONICET, Argentina Investigador CICBA

Large-scale simulations of Quantum Chromodynamics (QCD) which were performed on different parallel high-end supercomputers at the HLRZ supercomputing center, are introduced. Emphasis is laid on the hardware used and the parallelization strategies.

A review is presented of the possibilities for making precise tests of Quantum Chromodynamics at high energy e+e colliders operating at centr~of-m~s energies in the range 0.5 ~ Q < 2 TeV.

Color confinement is a consequence of an unbroken non-Abelian gauge symmetry and the resulting asymptotic freedom inherent in quantum chromodynamics. A qualitative sketch of its proof is presented.

It is shown that quantum chromodynamics based on asymptotic freedom and confinement exhibits the vector mode of chiral symmetry conjectured by Georgi. (∗): e-mail address: [email protected] PACS numbers: 11.30 Qc., 11.30.Rd., 12.38.Aw. Typeset using REVTEX

We review the recent results on D and D s meson semileptonic decays from CLEO-c, BABAR, and Belle. Comparisons with lattice quantum chromodynamics (LQCD) calculations and implications for B physics are also discussed.

Large scale simulations of Quantum Chromodynamics are extremely CPU time demanding. Today, simulations in a heterogeneous SIMD-MIMD environment can be an interesting step towards simulations on Teracomputers, as already available for Japanese and US groups.
