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…
