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…

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…

Optimised observables and new physics prospects in the penguin-mediated decays $B_{d (s)} \to K^{(*) 0} ϕ$

Aritra Biswas, Sébastien Descotes-Genon, Joaquim Matias +1

We study penguin-mediated $B ˉ_{d (s)} \to K ˉ^{* 0} (K^{* 0}) ϕ$ transitions, proposing a new optimised observable $L_{K^{*} ϕ}$ from the ratio of the corresponding branching ratios…

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…

A new puzzle in non-leptonic B decays

Aritra Biswas, Sébastien Descotes-Genon, Joaquim Matias +1

We propose a set of new optimized observables using penguin mediated $B ˉ_{d}$ and $B ˉ_{s}$ decays: $B ˉ_{d, s} \to K^{* 0} K ˉ^{* 0}$ , ${\bar B}_{d,s} \to K^{0} \bar{K}…
