Exploiting Perpendicular Momentum Distributions of Semileptonic Decays: $B ˉ_{s}^{0} \to D_{s}^{+} I^¼^{-} I^ˉ ½$ as a Case Study

Charles Earnshaw, Biljana Mitreska, Danny van Dyk

We derive the differential distribution of semileptonic decays with respect to the perpendicular momentum component of the final state hadron. The benefits and shortfalls arising f…

Towards a Global Analysis of the $b \to c u ˉ q$ Puzzle

Stefan Meiser, Danny van Dyk, Javier Virto

We study the nonleptonic decays $B ˉ_{s}^{0} \to D_{s}^{(*) +} I ¨ ^{-}$ and $B ˉ^{0} \to D^{(*) +} K^{-}$ within the Weak Effective Theory (WET) up to mass-dimension six. We revisit the c…

Communicating Likelihoods with Normalising Flows

Jack Y. Araz, Anja Beck, MÃ©ril Reboud +2

We present a machine-learning-based workflow to model an unbinned likelihood from its samples. A key advancement over existing approaches is the validation of the learned likelihoo…

A Simple Parametrisation of the Pion Form Factor

Matthew Kirk, Bastian Kubis, MÃ©ril Reboud +1

We discuss a novel and simple parametrisation of the pion vector form factor that transparently connects spacelike and timelike regions of the momentum transfer $q^{2}$ . Our parametr…

Dispersive Analysis of $B \to K^{(*)}$ and $B_{s} \to I ¨ $ Form Factors

We perform the first simultaneous dispersive analysis of the $B \to K$ , $B \to K^{*}$ , and $B_{s} \to I ¨ $ form factors. By means of an improved parametrization, we take into account the f…

Constraining $∣ V_{cs} ∣$ and physics beyond the Standard Model from exclusive (semi)leptonic charm decays

We study the available data on exclusive leptonic and semileptonic $c \to s ℓ^{+} I^½$ decays within the Standard Model and beyond. Our analysis accounts for theory correlations betwe…
