Running coupling constant and correlation length from Wilson loops

Massimo Campostrini, Paolo Rossi, Ettore Vicari

We consider a definition of the QCD running coupling constant $α (μ)$ related to Wilson loops of size $r \times t$ with arbitrary fixed $t / r$ . The schemes defined by these couplings…

Comment on A. Patrascioiu and E. Seiler's paper ``Nonuniformity of the $1/ N$ Expansion for Two-Dimensional $O (N)$ Models''

Massimo Campostrini, Paolo Rossi

We remind that the non-uniformity in the temperature of the $1/ N$ expansion for dimensionful quantities pointed out in Patrascioiu and Seiler's paper is not only compatible with bu…

Two dimensional SU(N)xSU(N) Chiral Models on the Lattice (II): the Green's Function

Paolo Rossi, Ettore Vicari

Analytical and numerical methods are applied to principal chiral models on a two-dimensional lattice and their predictions are tested and compared. New techniques for the strong co…
