Non-perturbative Aspects of Hot Qcd
نویسندگان
چکیده
I discuss some non-perturbative aspects of hot gauge theories as related to the unscreened static magnetic interactions. I first review some of the infrared divergences which cause the breakdown of the perturbation theory. Then I show that kinetic theory, as derived from quantum field theory, is a powerful tool to construct effective theories for the soft modes, which then can be treated non-perturbatively. The effective theory at the scale gT follows from a collisionless kinetic equation, of the Vlasov type. The effective theory at the scale gT is generated by a Boltzmann equation which includes the collision term for colour relaxation.

QCD and Quark/Hadron Matter
A brief review on the recent theoretical progress in hot/dense QCD is given. Special emphasis is put on the non-perturbative aspects of QCD plasma and the modification of hadron proporties near the critical temperature of chiral transition.
متن کاملThe pressure of hot QCD up to g 6 ln ( 1 / g )
The pressure of hot QCD up to g 6 ln(1/g) The free energy density, or pressure, of QCD has at high temperatures an expansion in the coupling constant g, known so far up to order g 5. We compute here the last contribution which can be determined perturbatively, g 6 ln(1/g), by summing together results for the 4-loop vacuum energy densities of two different three-dimensional effective field theor...

متن کاملRates for Non-perturbative Processes in Hot Non-abelian Plasmas
I will be discussing the rate for non-perturbative processes in hot non-Abelian plasmas. For me “hot” means high enough temperature that the running coupling α(T ) is small, that chemical potentials are ignorable, and that there is no spontaneous symmetry breaking. Examples of non-perturbative processes include chirality violation in hot QCD and baryon number violation in hot electroweak theory...
متن کاملThe leading non-perturbative coefficient in the weak-coupling expansion of hot QCD pressure
Using Numerical Stochastic Perturbation Theory within three-dimensional pure SU(3) gauge theory, we estimate the last unknown renormalization constant that is needed for converting the vacuum energy density of this model from lattice regularization to the MS scheme. Making use of a previous nonperturbative lattice measurement of the plaquette expectation value in three dimensions, this allows u...
