摘要：Algorithmic and technical progress achieved over the last few years makes QCD simulations with light dynamical quarks much faster than before. As a result lattices with pions as light as 250.300 MeV can be simulated with the present generation of computers. I review recent conceptual and numerical progress in this eld, with particular emphasis on results obtained and difculties encountered in simulations with signicantly smaller quark masses with respect to previous computations. I also attempt to compare physical results for pion masses and decay constants available to date in the two-avour theory with expectations from chiral perturbation theory.
