The decay-mode dependent scalar form factor is the only necessary theoretical ingredient for the relations. Otherwise, they combine measurable decay rates as a function of the invariant mass-squared of the lepton pair q2 in such a way that a universal decay-mode… 3 Citations • Physics • 2021 A model-independent analysis of a non-standard pseudoscalar contribution to leptonic meson decays (π,K,D,Ds and B) is presented.

A model-independent analysis of a non-standard scalar contribution to the pion decay in a lepton and a neutrino is presented. We discuss the necessity of such scalars in many models beyond the
