QED Corrections to $B^{-} \to I ¨ ^{-} I^ˉ ½_{I ¨} $

Claudia Cornella, Max FerrÃ©, Matthias KÃ¶nig +1

The paper computes the rate of the leptonic decay B⁻→τ⁻ν̄_τ including real and virtual QED corrections using a sequence of effective field theories, providing a factorized expressi…

The Simplest B Decay, Precisely

Claudia Cornella, Max FerrÃ©, Matthias KÃ¶nig +1

We derive the QCD $\times$ QED factorization theorem governing the leptonic decay $B^{-} \to I^¼^{-} I^ˉ ½_{I^} ¼ (I^^{3})$ at all orders in $I^\pm_{s}$ and $I^\pm$ . Electromagnetic corrections to this deca…

$B_{s}^{0} \to K^{0} K^{0}$ beyond the Standard Model

Yuval Grossman, Yosef Nir, Matthias Neubert +2

Within the Standard Model, the branching fraction of the rare decay $B_{s} \to K^{0} K ˉ^{0}$ is related to other decay rates and CP asymmetries through the approximate $S U (3)$ flavor s…

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…
