Abstract: (APS)

It has been commonly assumed that pseudoscalar contributions to the leptonic decay of charged mesons, like pions and kaons, is strongly constrained due to the helicity suppression present in the ratio

R_{l / l^{'}} = Γ (P \to l ν [γ]) / Γ (P \to l^{'} ν [γ])

, where

P

are the charged pseudoscalar meson and

l, l^{'} = e

,

μ

,

τ

. Here we show that if the effective couplings are proportional to the corresponding charged lepton masses (and also the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix), the constraints from

R_{l / l^{'}}

are entirely avoided, and a rather new large allowed region is permitted in the parameter space. In the case of the electron, we found a nontrivial region in the range

10^{- 4} ≲ (G^{η} / G_{F}) ≲ 10^{- 3}

, where

G^{η}

is the effective pseudoscalar coupling associated with a novel charged scalar field,

η

, and

G_{F}

is the Fermi constant. Furthermore, we show that this dependence of the pseudoscalar couplings on the charged lepton masses can naturally be associated with a critical class beyond the standard model physics, namely models without (leptonic) flavor-changing neutral currents in the scalar sector. The most known examples are the models that satisfy the so-called Glashow-Weinberg-Paschos theorem. Finally, we also point out that, in those cases, the decay rate is degenerated with the Standard Model prediction, possibly hiding the new physics effects in those decays.
