We review lattice studies of the color screening in quark-gluon plasma. put phenomena related to into context similar aspects other physical systems (electromagnetic plasma or cold nuclear matter). discuss onset and its signature significance QCD transition region, elucidate at which temperature extent weak-coupling picture based on hard thermal loop expansion, potential nonrelativistic QCD, di...

These lectures provide an overview of Quantum Chromodynamics (QCD), the SU (3) C gauge theory of the strong interactions. The running of the strong coupling and the associated property of Asymptotic Freedom are analyzed. Some selected experimental tests and the present knowledge of αs and the quark masses are briefly summarized. A short description of the QCD flavour symmetries and the dynamica...

QCD is the accepted (that is, the effective) theory of the strong interaction; studies at colliders are no longer designed to establish this. Such studies can now be divided into two categories. The first involves the identification of observables which can be both measured and predicted at the level of a few percent. Such studies parallel those of the electroweak sector over the past fifteen y...

Despite the many empirical successes of QCD, there are a number of intriguing experimental anomalies that have been observed in heavy avor hadroproduc-tion, in measurements of azimuthal correlations in deep inelastic processes, and in measurements of spin correlations in hadronic reactions. Such phenomena point to color coherence and multiparton correlations in the hadron wavefunc-tions and phy...

This Resource Letter provides a guide to the literature on Quantum Chromodynamics (QCD), the relativistic quantum field theory of the strong interactions. Journal articles, books, and other documents are cited for the following topics: quarks and color, the parton model, Yang-Mills theory, experimental evidence for color, QCD as a color gauge theory, asymptotic freedom, QCD for heavy hadrons, Q...

In theoretical physics, quantum chromodynamics (QCD) is a theory ofstrong interactions, a fundamental forcedescribing the interactions between quarksand gluons which make up hadrons such as the proton, neutron and pion. QCD is a type of Quantum field theory called a nonabelian gauge theory with symmetry group SU(3). The QCD analog of electric charge is a property called 'color'. Gluons are the ...

QCD To reduce the size of this section's PostScript file, we have divided it into two PostScript files. We present the following index: PART 1 Page # Section name 1 9.1 The QCD Lagrangian 2 9.2 The QCD coupling and renormalization scheme 6 9.3 QCD in deep-inelastic scattering 9 9.4 QCD in decays of the τ lepton 11 9.5 QCD in high-energy hadron collisions PART 2

The P and Y spectroscopies are analyzed in the framework of a recently proposed potential model which incorporates linear confinement and asymptotic freedom. Given the Regge slope a ' (a ' taken to be 1 GeV ') and the quantum-chromodynamics (QCD) scale parameter A (AM, taken to be 0.5 GeV, where MS refers to the modified minimal-subtraction scheme) the potential is completely determined.
