13 Jun 2005 | | Subject: | hep-lat hep-ph hep-th nucl-th | | Abstract: | We propose a new variant of the operator method for the computation of the equation of state of QCD, which yields positive pressure for all temperatures, including in the transition region. Using it on temporal lattices of 8, 10 and 12 sites, we obtained the continuum values of the pressure, P, energy density, epsilon, entropy density, s, the specific heat, C_v, and the speed of sound, C_s, in quenched QCD, for 0.9 le T/T_c le 3. This is the first direct estimate of C_s and C_v below T_c in QCD. We also test the approach to dimensional reduction and a conformal symmetric theory at high-temperature. | | Source: | arXiv, hep-lat/0506015 | | Services: | Forum | Review | PDF | Favorites | |
