Nf=2 QCD as a probe of confinement.
Adriano Di Giacomo


Abstract
A numerical analysis is made of the chiral transition of Nf=2 QCD on the lattice. The issue is relevant to understand the mechanism of color confinement. A finite size scaling analysis of the specific heat and of various susceptibilities unambiguously indicates that the transition is first order, although very weak , and weaker as the quark mass is increased. A large volume and small masses are indeed needed to detect the increase with volume of the specific heat and bistability in time histories.
