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…

Exploring $B \to π π, π K$ Decays at the High-Precision Frontier

Robert Fleischer, Ruben Jaarsma, Eleftheria Malami +1

The $B \to π π, π K$ system offers a powerful laboratory to probe strong and weak interactions. Using the isospin symmetry, we determine hadronic $B \to π π$ parameters from data where new…

Utilising $B \to π K$ Decays at the High-Precision Frontier

Robert Fleischer, Ruben Jaarsma, Eleftheria Malami +1

For about twenty years, $B \to π K$ decays are in the focus of $B$ -decay studies. We show that a correlation between the CP asymmetries of $B_{d}^{0} \to π^{0} K_{S}$ reveals a tension wit…

Towards New Frontiers with $B \to π K$ Decays

Robert Fleischer, Ruben Jaarsma, K. Keri Vos

Exploring correlations between the CP asymmetries of $B_{d}^{0} \to π^{0} K_{S}$ following from an isospin relation, we uncover new tensions with the Standard Model in data for neutral…

CP Violation in Leptonic Rare $B_{s}^{0}$ Decays as a Probe of New Physics

Robert Fleischer, Daniela Galárraga Espinosa, Ruben Jaarsma +1

The decay $B_{s}^{0} \to μ^{+} μ^{-}$ is a key probe for the search of physics beyond the Standard Model. While the current measurements of the corresponding branching ratio agree with the St…

In Pursuit of New Physics with $B_{s, d}^{0} \to ℓ^{+} ℓ^{-}$

Robert Fleischer, Ruben Jaarsma, Gilberto Tetlalmatzi-Xolocotzi

Leptonic rare decays of $B_{s, d}^{0}$ mesons offer a powerful tool to search for physics beyond the Standard Model. The $B_{s}^{0} \to μ^{+} μ^{-}$ decay has been observed at the Large Hadron…

Towards New Frontiers in the Exploration of Charmless Non-Leptonic $B$ Decays

Robert Fleischer, Ruben Jaarsma, K. Keri Vos

Non-leptonic $B$ decays into charmless final states offer an important laboratory to study CP violation and the dynamics of strong interactions. Particularly interesting are $B^0_s…

New Strategy to Explore CP Violation with $B_{s}^{0} \to K^{-} K^{+}$

Robert Fleischer, Ruben Jaarsma, K. Keri Vos

The $U$ -spin symmetry provides a powerful tool to extract the angle $γ$ of the Unitarity Triangle and the $B_{s}^{0}$ - $B ˉ_{s}^{0}$ mixing phase $ϕ_{s}$ from CP violation in the $B^0_s\t…
