Abstract: (APS)
We present the results of an analysis of 8141 Ke4 decays. These include (i) the form factors of the weak hadronic current and their dependences on the invariant di-lepton and di-pion masses, and (ii) the magnitude and dependence on invariant di-pion mass of the π−π scattering phase shift δs−δp.
