Theoretical status of the CKM Matrix
Alexander Lenz
In this talk I review the current status of the CKM matrix. A special emphasis is also given to several discrepancies between experiments and the standard model at the level of abo…
A simple relation for B_s-mixing
Alexander Lenz
We reinvestigate a simple relation between the semileptonic CP asymmetry a_{sl}^s, the decay rate difference ΔΓ_s, the mass difference ΔM_s and S_{ψϕ} extracted from the angular an…
Fourth Generation Majorana Neutrinos
Alexander Lenz, Heinrich Päs, Dario Schalla
We investigate the possibility of a fourth sequential generation in the lepton sector. Assuming neutrinos to be Majorana particles and starting from a recent - albeit weak - eviden…
Summary of WG4: "Lifetime, mixing and weak mixing phase in charm and beauty, including direct determination of V_{tx}
Michal Kreps, Alexander Lenz, Olivier Leroy
We present the summary of the Working Group on lifetimes, mixing and weak mixing phases in charm and beauty mesons at the CKM 2010 workshop. In the past year or so good progress wa…
Numerical updates of lifetimes and mixing parameters of B mesons
Alexander Lenz, Ulrich Nierste
We update the Standard-Model predictions for several quantities related to and mixing. The mass and width differences in the system read $ Δ…
