The K ℓ3 scalar form factors in the standard model

We discuss the predictions of the standard model for the scalar form factors of Kℓ3 decays. Our analysis is based on the results of chiral perturbation theory, large Nc estimates of low-energy couplings and dispersive methods. It includes a discussion of isospin-violating effects of strong and elect...

Description
Summary:We discuss the predictions of the standard model for the scalar form factors of Kℓ3 decays. Our analysis is based on the results of chiral perturbation theory, large Nc estimates of low-energy couplings and dispersive methods. It includes a discussion of isospin-violating effects of strong and electromagnetic origin.
