Impact of polarization observables and $B_{c} \to τ ν$ on new physics explanations of the $b \to c τ ν$ anomaly

Monika Blanke, Andreas Crivellin, Stefan de Boer +4

The combined analysis of the BaBar, Belle, and LHCb data on $B \to D τ ν$ , $B \to D^{*} τ ν$ and $B_{c} \to J /Ψ τ ν$ decay observables shows evidence of physics beyond the Standard Model (SM).…

Charm decays

Stefan de Boer

The importance of charm decays in the context of flavor is motivated. A theory overview on recent developments in leptonic and semileptonic decays, hadronic two-body decays, and ra…

Null tests from angular distributions in $D \to P_{1} P_{2} l^{+} l^{-}$ , $l = e, μ$ decays on and off peak

Stefan de Boer, Gudrun Hiller

We systematically analyze the full angular distribution in $D \to P_{1} P_{2} l^{+} l^{-}$ decays, where $P_{1, 2} = π, K$ , $l = e, μ$ . We identify several null tests of the standard model (SM).…

Rare radiative charm decays in the standard model and beyond

Stefan de Boer

Motivated by the recent measurement of $D^{0} \to ρ^{0} γ$ improved standard model (SM) predictions for branching ratios and CP asymmetries of radiative charm decay are given. Weak annihi…

Opportunities with (semi)leptonic rare charm decays

Stefan de Boer

We study (semi)leptonic rare charm decays and its opportunities in searches for physics beyond the Standard Model (BSM). In particular, we analyse the impact of potential BSM physi…
