CP Violation in $D^{0} \to K_{S} K_{S}$

Ulrich Nierste, Stefan Schacht

The direct CP asymmetry $a_{C P}^{dir} (D^{0} \to K_{S} K_{S})$ involves exchange diagrams which are induced at tree level in the Standard Model. Since the corresponding top…

Sum Rules of Charm CP Asymmetries beyond the SU(3) $_{F}$ Limit

Sarah Müller, Ulrich Nierste, Stefan Schacht

We find new sum rules between direct CP asymmetries in $D$ meson decays with coefficients that can be determined from a global fit to branching ratio data. Our sum rules eliminate…

Lepton-flavour violating $B$ decays in generic $Z^{'}$ models

Andreas Crivellin, Lars Hofer, Joaquim Matias +3

LHCb has reported deviations from the Standard Model in $b \to s μ^{+} μ^{-}$ transitions for which a new neutral gauge boson is a prime candidate for an explanation. As this gauge boson…

Topological amplitudes in $D$ decays to two pseudoscalars: a global analysis with linear $S U (3)_{F}$ breaking

Sarah Müller, Ulrich Nierste, Stefan Schacht

We study decays of $D^{0}$ , $D^{+}$ , and $D_{s}^{+}$ mesons into two pseudoscalar mesons by expressing the decay amplitudes in terms of topological amplitudes. Including consistently SU(3)…

Penguin contributions to CP phases in $B_{d, s}$ decays to charmonium

Philipp Frings, Ulrich Nierste, Martin Wiebusch

The precision of the CP phases $2 β$ and $2 β_{s}$ determined from the mixing-induced CP asymmetries in $B_{d} \to J / ψ K_{S}$ and $B_{s} \to J / ψ ϕ$ , respectively, is limited by the unknown long-…
