| dc.description.abstract | We calculate the perturbative value of the free energy in Lattice QCD, up to three loops. Our calculation is performed using Wilson gluons and the Sheikholeslami-Wohlert (clover) improved action for fermions. The free energy is directly related to the average plaquette. To carry out the calculation, we compute all relevant Feynman diagrams up to 3 loops, using a set of automated procedures in Mathematica | en |
| dc.description.abstract | numerical evaluation of the resulting loop integrals is performed on finite lattices, with subsequent extrapolation to infinite size. The results are presented as a function of the fermion mass m, for any S U (Nc) gauge group, and for an arbitrary number of fermion flavors. In order to enable independent comparisons, we also provide the results on a per diagram basis, for a specific mass value. © 2007 Elsevier B.V. All rights reserved. | en |
