Dispersive description of the $K \to π ℓ^{+} ℓ^{-}$ radiative amplitudes

Véronique Bernard, Sébastien Descotes-Genon, Marc Knecht +1

We propose a description of the $K^{+}$ , $K_{S}$ radiative decay form factors $W_{+}$ , $W_{S}$ based on general properties of analyticity and unitarity. Starting from the simple considerat…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…

Predictions for the rare kaon decays $K_{S, L} \to π^{0} ℓ^{+} ℓ^{-}$ from QCD in the limit of a large number of colours

Giancarlo D'Ambrosio, Marc Knecht

The long-distance and non-local parts of the form factors describing the single-photon mediated $K_{S, L} \to π^{0} γ^{*} \to π^{0} ℓ^{+} ℓ^{-}$ ( $ℓ = e, μ$ ) transitions in the standard mod…
