Improved Theory Predictions and Global Analysis of Exclusive boldsymbol{bto sμ^+μ^-} Processes
read the original abstract
We provide improved Standard Model theory predictions for the exclusive rare semimuonic processes $B\to K^{(*)}\mu^+\mu^-$ and $B_s\to\phi\mu^+\mu^-$. Our results are based on a novel parametrization of the non-local form factors, which manifestly respects a recently developed dispersive bound. We critically compare our predictions to those obtained in the framework of QCD factorization. Our predictions provide, for the first time, parametric estimates of the systematic uncertainties due to non-local contributions. Comparing our predictions within the Standard Model to available experimental data, we find a large tension for $B\to K\mu^+\mu^-$. A simple model-independent analysis of potential effects beyond the Standard Model yields results compatible with other approaches, albeit with larger uncertainties for the $B\to K^*\mu^+\mu^-$ and $B_s\to \phi\mu^+\mu^-$ decays. Our approach yields systematically improvable predictions, and we look forward to its application in further analyses beyond the Standard Model.

A Dispersive Look at Rare $B$-meson Semileptonic Decays
A global fit of b→s ℓ+ℓ− and b→s νν data finds that hadronic charm-loop effects, not a new short-distance coupling C9, can explain the observed anomalies.

A Dispersive Look at Rare $B$-meson Semileptonic Decays
Lattice-only Dispersive Matrix form factors enlarge large-recoil uncertainties and, with new angular data, favour long-distance hadronic effects over a short-distance C9 New Physics shift.

Impact of Hadronic Resonances on $B\to K^{(*)}\tau^+\tau^-$ decays
Including resonant contributions from LHCb muon data enhances standard model predictions for B to K(*) tau tau decays and makes short-distance new physics comparable to or larger than resonant effects over the full q2 range.
