Description
We discuss a novel approach, based on spectral reconstruction techniques, which circumvents the well-known problem of the analytic continuation from Minkowskian to Euclidean time for hadronic processes above kinematical thresholds. The approach is discussed for the specific case of the radiative decays of pseudoscalar mesons
These processes, which give access to the rare decays
the lattice due to the presence of intermediate states which hinder the analytic continuation to Euclidean time when the photon off-shellness
