A data-driven approach to η and η′ Dalitz decays
Data-driven model-independent predictions for the dilepton invariant mass spectra and branching ratios of the single and double Dalitz decays η(′) → ℓ+ℓ− γ and η(′) → ℓ+ℓ− ℓ+ℓ− (ℓ = e or μ) are provided by means of an approach based on the use of rational approximants applied to the available experi...
