Larger physical volume with a noncompact lattice regularization of SU(N) theories
Giuseppe Di Carlo, Fabrizio Palumbo, Roberto Scimia
Recently it has been found that in a noncompact formulation of the SU(2) gauge theory on a lattice the physical volume is larger than in the Wilson theory with the same number of s…

Lattice QCD and chiral mesons
Sergio Caracciolo, Fabrizio Palumbo, Roberto Scimia
The standard QCD action is improved by the addition of irrelevant operators built with chiral composites. An effective Lagrangian is derived in terms of auxiliary fields, which has…
