Experimental tests of QCD predictions for event shape distributions combining contributions from hard and soft processes are discussed. The hard processes are predicted by perturbative QCD calculations. The soft processes cannot be calculated directly using perturbative QCD, they are treated by a power correction model based on the analysis of infrared renormalons. Furthermore, an analysis of t...

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). Understanding QCD thermodynamics from QCD spectral properties has its own importance. Also it has a close connection to phenomenological analyses of the lattice data as well as experimental data on the basis of ha...

The results of LO Fixed point QCD (FP-QCD) analysis of the CCFR data for the nucleon structure function xF3(x,Q 2) are presented. The predictions of FPQCD, in which αs(Q 2) tends to a nonzero coupling constant α0 as Q 2 → ∞ , are in good agreement with the data. The description of the data is even better than that in the case of LO QCD. The FP-QCD parameter α0 is determined with a good accuracy...

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...

A physical characterization of Landau singularities is emphasized, which should trace the lower boundary N f of the conformal window in QCD and supersymmetric QCD. A natural way to disentangle “perturbative” from “non-perturbative” contributions to amplitudes below N f is suggested. Assuming an infrared fixed point persists in the perturbative part of the QCD coupling even below N f leads to th...

Using the replica method, we analyze the mass dependence of the QCD 3 partition function in a parameter range where the leading contribution is from the zero momentum Goldstone fields. Three complementary approaches are considered in this article. First, we derive exact relations between the QCD 3 partition function and the QCD 4 partition function continued to half-integer topological charge. ...
