Determining QCD Low-Energy Couplings from lattice simulations
/ Authors
/ Abstract
Different strategies for the computation of QCD low-energy couplings by matching lattice QCD with the chiral effective theory are reviewed. After recalling the main features of the chiral effective theory in the epsilon- and p- regimes, the current status of the determination of leading order (Sigma, F) and next-to-leading order (l_i, L_i) low-energy constants is summarised, focusing in particular on recent results obtained with N_f=2 and N_f=2+1 simulations.
