Nonlocal form factor of chromomagnetic penguin in $B \to K ℓ^{+} ℓ^{-}$ from QCD light-cone sum rules

T. Hurth, A. Khodjamirian, F. Mahmoudi +3

The branching fraction of the $B \to K ℓ^{+} ℓ^{-}$ decay has been measured recently by the LHC experiments, showing a deviation from theory predictions based on the Standard Model…

Data-driven analyses and model-independent fits for present $b \to s ℓℓ$ results

T. Hurth, F. Mahmoudi, Y. Monceaux +1

We present a critical assessment of the present $B$ anomalies in the exclusive $b \to s ℓℓ$ mode based on the QCD factorisation (QCDf) approach. In particular, we analyse the…

Potential of light-cone sum rules without semiglobal quark-hadron duality

A. Carvunis, F. Mahmoudi, Y. Monceaux

This work addresses the calculation of local form factors involved in the theoretical predictions of semileptonic $B$ -meson decays at low $q^{2}$ . We present a new approach to the me…

New LCSR predictions for hadronic form factors

Y. Monceaux

We present an overview of a novel approach to the QCD Light-Cone Sum Rule method, employing $B$ -meson Light-Cone Distribution Amplitudes. This method circumvents the semi-global qu…
