Abstract

© Article funded by SCOAP3 and published under licence by Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences and IOP Publishing Ltd. The dilepton invariant mass spectra and integrated branching ratios of the single and double Dalitz decays P → 1+1-γ and P → 1+1-1+1- (P=π0,η,η'; 1=e or μ) are predicted by means of a data-driven approach based on the use of rational approximants applied to π0,η and η' transition form factor experimental data in the space-like region.
