We show how such a situation can be used to determine the couplings of the low energy chiral Lagrangian from lattice simulations, applying chirally invariant formulations of lattice fermions.11 pages, 4 figures, contribution to the NIC proceedings 2003Computational PhysicsHigh Energy Physics - LatticeHigh Energy Physics - Phenomenologytext
