Zooming into CP violation in $B_{(s)} \to hh$ Decays

Robert Fleischer, Ruben Jaarsma, K. Keri Vos

The LHCb collaboration has recently reported the first observation of CP violation in the penguin-dominated $B_{s}^{0} \to K^{-} K^{+}$ decay and further new measurements, indicating differe…

Mapping out the Space for New Physics with Leptonic and Semileptonic $B_{(c)}$ Decays

Robert Fleischer, Ruben Jaarsma, Gilberto Tetlalmatzi-Xolocotzi

Decays of $B$ mesons with leptons in the final state offer an interesting laboratory to search for possible effects of physics from beyond the Standard Model. In view of puzzling p…

Testing Lepton Flavour Universality with (Semi)-Leptonic $D_{(s)}$ Decays

Robert Fleischer, Ruben Jaarsma, Gabriël Koole

Data in $B$ -meson decays indicate violations of lepton flavour universality, thereby raising the question about such phenomena in the charm sector. We perform a model-independent a…

Probing Lepton Universality with (Semi)-Leptonic B decays

Giovanni Banelli, Robert Fleischer, Ruben Jaarsma +1

The most recent measurements of the observables $R_{D^{(*)}}$ are in tension with the Standard Model offering hints of New Physics in $b \to c ℓ ν ˉ_{ℓ}$ transitions…

Probing New Physics in $B \to π K$ Decays

Robert Fleischer, Ruben Jaarsma, Eleftheria Malami +1

Over the last two decades, $B \to π K$ modes have received a lot of attention. They are particularly interesting since the main contribution to these decays comes from QCD penguin t…

Decoding (Pseudo)-Scalar Operators in Leptonic and Semileptonic $B$ Decays

Giovanni Banelli, Robert Fleischer, Ruben Jaarsma +1

We consider leptonic $B^{-} \to ℓ^{-} ν ˉ_{ℓ}$ and semileptonic $B ˉ \to π ℓ^{-} ν ˉ_{ℓ}$ , $B ˉ \to ρ ℓ^{-} ν ˉ_{ℓ}$ decays and present a strategy to determine short-d…
