A Dispersive Treatment of Kℓ4 Decays
Kℓ4 are for several reasons an especially interesting decay channel of K mesons: Kℓ4 decays allow an accurate measurement of a combination of S-wave ππ scattering lengths, one form factor of the decay is connected to the chiral anomaly and the decay is the best source for the determination of some l...
