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…

Structure-Dependent QED Effects in Exclusive B Decays at Subleading Power

Claudia Cornella, Matthias KÃ¶nig, Matthias Neubert

We derive a factorization theorem for the structure-dependent QED effects in the weak exclusive process $B^{-} \to ℓ^{-} I^ˉ ½_{ℓ}$ , i.e., effects probing the internal structure of t…

Testing the Froggatt-Nielsen Mechanism with Lepton Flavor and Number Violating Processes

Claudia Cornella, David Curtin, Gordan Krnjaic +1

The Froggatt-Nielsen (FN) mechanism offers an elegant explanation for the observed masses and mixings of Standard Model fermions. In this work, we systematically study FN models in…

Precision Tests in $b \to s ℓ^{+} ℓ^{-}$ ( $ℓ = e, I^¼$ ) at FCC-ee

Marzia Bordone, Claudia Cornella, Joe Davighi

The rare semi-leptonic decays $B \to K^{*} ℓ^{+} ℓ^{-}$ , with $ℓ = e, I^¼$ , are highly sensitive to new physics (NP) due to their suppression in the Standard Model (SM). Current L…
