New physics effects in tree-level decays
Joachim Brod, Alexander Lenz, Gilberto Tetlalmatzi-Xolocotzi +1
We critically review the assumption that no new physics is acting in tree-level -meson decays and study the consequences for the ultimate precision in the direct determination o…
Investigating bounds on decoherence in quantum mechanics via B and D-mixing
Alexander Lenz, David Hodges, Daniel Hulme +4
We investigate bounds on decoherence in quantum mechanics by studying and -mixing observables, making use of many precise new measurements, particularly from the LHC and B f…
-mixing in and beyond the Standard model
Alexander Lenz
We review the status of mixing of neutral -mesons, including a discussion of the current precision of Standard Model (SM) predictions as well as the space that is left for effec…
Lifetimes and HQE
Alexander Lenz
Kolya Uraltsev was one of the inventors of the Heavy Quark Expansion (HQE), that describes inclusive weak decays of hadrons containing heavy quarks and in particular lifetimes. Bes…
Selected Topics in Heavy Flavour Physics
Alexander Lenz
We review the status of flavour physics in spring 2014. The numerous accurate new measurements of flavour experiments have enabled us to test our theoretical understanding of flavo…
On new physics in
Christoph Bobeth, Ulrich Haisch, Alexander Lenz +2
Motivated by the recent measurement of the dimuon asymmetry by the DØ collaboration, which could be interpreted as an enhanced decay rate difference in the neutral -meson syst…
