N-ality and topology at finite temperature
L. Del Debbio, H. Panagopoulos, E. Vicari
We study the spectrum of confining strings in SU(3) pure gauge theory, in different representations of the gauge group. Our results provide direct evidence that the string spectrum…
O(a) improved QCD: The 3-loop beta-function, and the critical hopping parameter
A. Bode, H. Panagopoulos, Y. Proestos
We calculate the 3-loop bare -function of QCD, formulated on the lattice with the clover fermionic action. The dependence of our result on the number of colors , the number o…
Spectrum of k-string tensions in SU(N) gauge theories
L. Del Debbio, H. Panagopoulos, P. Rossi +1
We compute, for the four-dimensional SU(4) and SU(6) gauge theories formulated on a lattice, the string tensions sigma_k related to sources with Z_N charge k, using Monte Carlo sim…
Field strength correlations in the QCD vacuum at short distance
Adriano Di Giacomo, Enrico Meggiolaro, Haralambos Panagopoulos
We determine by numerical simulations on a lattice the gauge--invariant two--point correlation function of the gauge field strengths in the QCD vacuum, down to a distance of 0.1 fm…
