Description
The
dilepton invariant mass spectra and branching ratios of the single and double Dalitz decays
$\mathcal{P}\to\ell^{+}\ell^{-}\gamma$ and $\mathcal{P}\to\ell^{+}\ell^{-}\ell^{+}\ell^{-}$
($\mathcal{P}=\pi^{0}, \eta, \eta^{\prime}$; $\ell=e$ or $\mu$) are predicted by means of a
data-driven model-independent approach based on the use of rational approximants applied to
$\pi^{0}, \eta$ and $\eta^{\prime}$ transition form factor experimental data in the space-like region.
Summary
A data-driven model-independent approach to $\pi^{0}, \eta$ and $\eta^{\prime}$ single and double Dalitz decays
