ec 2 00 1 Evaporation of the gluon condensate : a model for pure gauge SU ( 3 ) c phase transition
نویسنده
چکیده
We interpret lattice data for the equation of state of pure gauge SU(3)c by an evaporation model. At low temperatures gluons are frozen inside the gluon condensate, whose dynamics is described in terms of a dilaton lagrangian. Above the critical temperature quasifree gluons evaporate from the condensate: a first order transition is obtained by minimizing the thermodynamical potential of the system. Fixing the model parameters to independent quantities, we can reproduce the value of the critical temperature suggested by lattice QCD. It is also possible to obtain a value for the latent heat in reasonable agreement with the results of the lattice calculations.

متن کاملGauge – invariant field – strength correlators in pure
We study by numerical simulations on a lattice the behaviour of the gauge–invariant two– point correlation functions of the gauge–field strengths across the deconfinement phase transition, both for the pure–gauge SU(3) theory and for full QCD with two flavours. Quenched data agree within errors with previous determinations, but have much higher statistics. A best–fit analysis of the data has be...
متن کاملساختار فاز میدانهای پیمانه‌ای شبکه‌ای دو بعدی U(N) با کنش مختلط
We study the phase structure of two dimensional pure lattice gauge theory with a Chern term. The symmetry groups are non-Abelian, finite and disconnected sub-groups of SU(3). Since the action is imaginary it introduces a rich phase structure compared to the originally trivial two dimensional pure gauge theory. The Z3 group is the center of these groups and the result shows that if we use one ...

Deconfined regions created in heavy ion collisions are bordered by the confined phase. We discuss boundary conditions (BCs) to model a cold exterior. Monte Carlo simulations of pure SU(3) lattice gauge theory with thus inspired BCs show scaling. Corrections to usual results survive in the finite volume continuum limit and we estimate them in a range from L = 5− 10 fermi as function of the volum...

Many new results have poured forth from RHIC ( √ s = 130A GeV). Several appear to be qualitatively different from those at the SPS ( √ s = 17A GeV). “Dynamical” fluctuations in the average transverse momentum, pt, are almost three times larger than at the SPS [1]. Observed HBT radii are small, ∼ 5−7 fm [2], and average transverse boost velocities are large, ∼ .6 c [3]. In particular, that the H...
