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…

A dispersive approach to the CP conserving $K \to π ℓ^{+} ℓ^{-}$ radiative decays

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

We reconsider the constraints on the form factors $W_{+} (s)$ and $W_{S} (s)$ , describing the radiative decay modes $K^{+} \to π^{+} ℓ^{+} ℓ^{-}$ and $K_{S} \to π^{0} ℓ^{+} ℓ^{-}$ , associated wi…

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…

A dispersive study of final-state interactions in $K \to π π π$ amplitudes

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

A system of dispersive representations of the Omnès-Khuri-Treiman-Sawyer-Wali type for the final-state interactions in the amplitudes of the $K \to π π π$ weak transitions is construct…
