CP violation in $B_{(s)} \to ϕ K$ decays: Standard Model and isospin-dependent New Physics

Robert Fleischer, Jelle Groot, K. Keri Vos

The penguin-dominated $B \to ϕ K$ decays provide sensitive probes of physics beyond the Standard Model. Interpreting them at increasing experimental precision requires control of doub…

A Standard Model analysis of $D^{0} \to π^{-} π^{+}, K^{-} K^{+}, K_{S}^{0} K_{S}^{0}$

Robert Fleischer, Maria Laura Piscopo, K. Keri Vos +1

We investigate the Standard Model (SM) description of the singly Cabibbo-suppressed charm decays $D^{0} \to π^{-} π^{+}$ , $D^{0} \to K^{-} K^{+}$ and $D^{0} \to K_{S}^{0} K_{S}^{0}$ . Using factori…

Probes for CP Violation in B Decays at the FCC: A Theorist's Perspective

Robert Fleischer

CP violation offers powerful probes to explore the quark-flavour sector, where decays of B mesons have been key players since decades. I discuss a variety of probes ranging from no…

CP Violation in $B_{(s)} \to ϕ K$ Decays: Standard Model Benchmarks and Isospin-Breaking New Physics

Robert Fleischer, Jelle Groot, K. Keri Vos

The penguin loop-suppressed $B \to ϕ K$ decays are highly sensitive to contributions of hypothetical heavy new particles. Particularly interesting probes for testing the Standard Mode…

Standard Model Benchmarks for $D^{0} \to K^{-} K^{+}, π^{-} π^{+}, K_{S}^{0} K_{S}^{0}$ Decays

Robert Fleischer, Maria Laura Piscopo, K. Keri Vos +1

The non-leptonic $D^{0} \to K^{-} K^{+}$ and $D^{0} \to π^{-} π^{+}$ decays are powerful probes of the Standard Model and are related to each other through the $U$ -spin symmetry of the strong int…

How to tame penguins: Advancing to high-precision measurements of $ϕ_{d}$ and $ϕ_{s}$

Kristof De Bruyn, Robert Fleischer, Eleftheria Malami

The complex phases $ϕ_{d}$ and $ϕ_{s}$ , associated with the mixing between neutral $B_{q}^{0}$ and $B ˉ_{q}^{0}$ mesons ( $q \in {d, s}$ ), are key observables to test the Standard Model and s…
