A dispersive treatment of Kℓ4 decays

The Kℓ4 decay is one of the best sources of information on some low-energy constants of chiral perturbation theory (χPT). We present a dispersive approach to Kℓ4 decays, which takes rescattering effects fully into account. The dispersion relation treats both experimentally accessible form factors s...
