      abstract     = {We construct several classes of hadronic matrix elements
                      and relate them to the low-energy constants in Chiral
                      Perturbation Theory that describe the electromagnetic
                      effects in the semileptonic beta decay of the pion and the
                      kaon. We propose to calculate them using lattice QCD, and
                      argue that such a calculation will make an immediate impact
                      to a number of interesting topics at the precision frontier,
                      including the outstanding anomalies in |V$_{us}$| and the
                      top-row Cabibbo-Kobayashi-Maskawa matrix unitarity.},
