The Semileptonic B Frontier: LHC, B-factories, Lattice QCD & the Hunt for Precision

F. De Fazio, P. De Simone, M. Fedele +33

This review document summarizes the main outcomes and key theoretical and experimental developments discussed at the workshop ``The Semileptonic $B$ Frontier: LHC, $B$ -Factories, L…

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

Marzia Bordone, Gino Isidori, Arianna Tinari

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

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

Sebastiano Covone, Pol Morell, Arianna Tinari

We study the implications of an approximate $U (2)^{5}$ flavor symmetry at the TeV scale, under the assumption of new physics predominantly coupled to the third-generation fermions, f…

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…

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…

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…

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 physics in $B \to K^{(*)} ℓ^{+} ℓ^{-}$ : a data-driven analysis

Marzia Bordone, Gino isidori, Sandro Mächler +1

We analyze data on $B \to K μ^{+} μ^{-}$ and $B \to K^{*} μ^{+} μ^{-}$ decays in the whole dilepton invariant mass spectrum with the aim of disentangling short- vs. long-distance contributions. Th…

New tests of short-distance dynamics in $b \to s ℓ ˉ ℓ$ decays

Arianna Tinari

The rare $B \to K^{(*)} ℓ ˉ ℓ$ decays exhibit a long-standing tension with Standard Model (SM) predictions, which can be attributed to a lepton-universal short-distance $…

Semi-inclusive $b \to s ℓ ˉ ℓ$ transitions at high $q^{2}$

Gino Isidori, Zachary Polonsky, Arianna Tinari

We present an updated Standard Model (SM) estimate of the inclusive $b \to s ℓ ˉ ℓ$ rate at high dilepton invariant mass ( $q^{2} \geq 15 GeV^{2}$ ). We show that this estima…
