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

VÃ©ronique Bernard, SÃ©bastien Descotes-Genon, Marc Knecht +1

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

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

VÃ©ronique Bernard, SÃ©bastien 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…

Flavor Physics at the CEPC: a General Perspective

Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron +147

We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is d…
