The Transition between Perturbative and Non-perturbative Qcd
نویسنده
چکیده
We study both polarized and unpolarized proton structure functions in the kinematical region of large Bjorken x and four-momentum transfer of few GeV. In this region the phenomenon of parton-hadron duality takes place between the smooth continuation of the deep inelastic scattering curve and the average of the nucleon resonances. We present results on a perturbative-QCD analysis using all recent accurate data with the aim of extracting the infrared behavior of the nucleon structure functions.

Gluon Condensate and Parton Propagation in a Quark-gluon Plasma
Finite temperature QCD can be used to describe properties of a quark-gluon plasma (QGP) possibly created in the fireball of relativistic heavy ion collisions and in the early Universe. There are two different methods available, namely lattice QCD and perturbation theory. Lattice QCD is a non-perturbative method, which can be used at all temperatures above and below the phase transition. However...

This series of lectures consists of two parts. In the first part the foundations of perturbative and non perturbative formulation are discussed. The ambiguity in the definition of vacuum condensates is then analyzed. In the second part the symmetry patterns of the deconfining phase transition are discussed.
متن کاملProbing non-perturbative QCD through hadronic matrix elements extracted from exclusive hard processes
QCD is the theory of strong interactions and non-perturbative methods have been developed to address the confinement property of QCD. Many experimental measurements probe the confining dynamics, and it is well-known that hard scattering processes allow the extraction of non perturbative hadronic matrix elements. To study exclusive hard processes, such as electromagnetic form factors and reactio...

Using recent measurements of the b-quark fragmentation distribution obtained in e+e− → bb events registered at the Z pole, the non-perturbative QCD component of the distribution has been extracted independently of any hadronic physics modelling. This distribution depends only on the way the perturbative QCD component has been defined. When the perturbative QCD component is taken from a parton s...
