One constraint to kill them all?
Luca Di Luzio, Matthew Kirk, Alexander Lenz
Many new physics models that explain the intriguing anomalies in the -quark flavour sector are severely constrained by -mixing, for which the Standard Model prediction and…
Dimension-six matrix elements for meson mixing and lifetimes from sum rules
M. Kirk, A. Lenz, T. Rauh
The hadronic matrix elements of dimension-six operators are crucial inputs for the theory predictions of mixing observables and lifetime ratios in the and system.…
Charming Dark Matter
Thomas Jubb, Matthew Kirk, Alexander Lenz
We have considered a model of Dark Minimal Flavour Violation (DMFV), in which a triplet of dark matter particles couple to right-handed up-type quarks via a heavy colour-charged sc…
Charming new physics in rare B-decays and mixing?
Sebastian Jäger, Matthew Kirk, Alexander Lenz +1
We conduct a systematic study of the impact of new physics in quark-level transitions on -physics, in particular rare -decays and -meson lifetime obser…
