Cooling and the string tension in lattice gauge theories
Campostrini, M.; Di Giacomo, A.; Maggiore, M.; Panagopoulos, Haralambos G.; Vicari, E. (1989)We explore the possibility of improving the determination of the string tension using the cooling method. We present preliminary results for the gauge group SU(2): We find that statistical errors are drastically reduced ...

String tension and flux tubes on the lattice
Campostrini, M.; Di Giacomo, A.; Maggiore, M.; Olejník, S.; Panagopoulos, Haralambos G.; Vicari, E. (1990)We use the cooling technique to study the string tension in pure SU(2) gauge theory. We find that statistical errors are drastically reduced and at the same time the string tension is preserved through many cooling steps. ...

The two-loop average plaquette on the BCH lattice
Maggiore, M.; Panagopoulos, Haralambos G. (1988)We perform a two-loop calculation of the average triangular plaquette on the body-centered hypercubic (BCH) lattice. Combining our result with Monte Carlo SU(2) data on this lattice, we estimate the value of the gluon ...

Universality and the parameter on a body-centered hypercubic lattice
Di Giacomo, A.; Maggiore, M.; Panagopoulos, Haralambos G. (1987)We calculate the relationship between the coupling constants of the simple hypercubic and the body-centered hypercubic lattice, to one-loop order, using the background-field method. This corresponds to determining the ratio ...
