Padé Improvement of the Free Energy in High Temperature QCD
نویسنده
چکیده
Padé approximants (PA) are constructed from the perturbative coefficients of the free energy through O(g5) in hot QCD. PA is shown to reduce the renormalization-scale dependence substantially even at temperature (T ) as low as 250 MeV. Also, Padé summation predicts that the free energy does not deviate more than 10 % from the Stefan-Boltsman limit for T > 250 MeV. PACS numbers: 12.38Cy, 12.38.Mh, 11.10.Wx Typeset using REVTEX

The three-loop free energy for high-temperature QED and QCD with fermions
We compute the free energy density for gauge theories, with fermions, at high temperature and zero chemical potential. Specifically, we analytically compute the free energy through O(g4), which requires the evaluation of threeloop diagrams. This computation extends our previous result for pure gauge QCD.
متن کاملTHERMODYNAMICS OF QCD AT HIGH TEMPERATURE a
A hierarchy of effective field theories is used to separate the contributions from different momentum scales and to calculate the free energy of QCD at high temperature in powers of the coupling constant up to order g 5. The behavior of the perturbative series will also be discussed.
متن کاملInvestigating the Energy Efficiency of TEX High Energy Derivatives with Different Carbon Fuller Nano Structures under Different Temperature Conditions by DFT Method
In this study, high energy energy derivatives of TEX with different carbon-containing fullerenes at different temperature conditions were studied using density functional theory. For this purpose, the materials were first geometric optimized, then the thermodynamic parameters were calculated for all of them. Then, the process of changing the energy-dependent parameters such as specific heat cap...
متن کاملAsymptotic Freedom and Dirichlet String Theory
Fixed angle scattering at high energy in a string theory with boundaries satisfying Dirichlet conditions (Dirichlet strings) inD = 4 is shown to have logarithmic dependence on energy, in addition to the power-like behavior known before. High temperature free energy also depends logarithmically on temperature. Such a result could provide a matching mechanism between strings at long distance and ...
متن کاملData Envelopment Analysis from simulation on the Lattice QCD using CCR model
One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...
