Constraints on lepton-flavor mixing with third-generation new physics

Sebastiano Covone, Pol Morell, Arianna Tinari

The paper investigates how an approximate U(2)^5 flavor symmetry with new physics mainly coupled to third‑generation fermions constrains mixing between second‑ and third‑generation…

Disentangling short- vs. long-distance dynamics in $B \to K^{*} I^¼^{+} I^¼^{-}$

Marzia Bordone, Gino Isidori, Arianna Tinari

We present an updated data-driven analysis of short- vs. long-distance dynamics in $B \to K^{*} I^¼^{+} I^¼^{-}$ . The analysis is based on the recent LHCb measurement of the full angular di…

Charm rescattering in $B^{0} \to K^{0} ℓ ˉ ℓ$ : an improved analysis

Gino Isidori, Zachary Polonsky, Arianna Tinari

We improve upon previous explicit estimates of charm rescattering contributions to the decay $B^{0} \to K^{0} ℓ ˉ ℓ$ by including contributions from dipole interactions with the…

Theoretical Aspects of $b \to s ℓ ˉ ℓ$ Decays

Arianna Tinari

Flavor-changing neutral current decays such as $b \to s ℓ ˉ ℓ$ are highly suppressed in the Standard Model (SM) and therefore provide sensitive tests for new physics. Per…

Explicit estimate of charm rescattering in $B^{0} \to K^{0} ℓ ˉ ℓ$

Gino Isidori, Zachary Polonsky, Arianna Tinari

We analyze $B^{0} \to K^{0} ℓ ˉ ℓ$ long-distance contributions induced by the rescattering of a pair of charmed and charmed-strange mesons. We present an explicit estimate of…

Short- vs Long-Distance Dynamics in $b \to s ℓ ˉ ℓ$ Decays

Arianna Tinari

The tension of $B \to K^{(*)} ℓ ˉ ℓ$ decays with the Standard Model (SM) can be attributed to a short-distance (SD) $b s ℓ ˉ ℓ$ interaction. We show two methods to disen…
