In this work we present a new calculation of the Wilson Coefficients c1 and c2 of the Effective Weak Hamiltonian to all-orders in alpha_s, using lattice simulations. Given the current availability of lattice spacings we restrict our calculation to unphysically light W-bosons around 2 GeV and we demonstrate how both Wilson Coefficients can be obtained with controlled systematic uncertainties.
