B, D and K decays (2008)
Journal Article
Buchalla, G., Komatsubara, T., Muheim, F., Silvestrini, L., Artuso, M., Asner, D., …Zwicky, R. (2008). B, D and K decays. The European Physical Journal C, 57(1-2), 309-492. https://doi.org/10.1140/epjc/s10052-008-0716-1

The present report documents the results of Working Group 2: B, D and K decays, of the workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through March 2007. With the advent of the LHC, we will be able to probe New Physics (NP)... Read More about B, D and K decays.

The theoretical status of B¯ − B-mixing and lifetimes of heavy hadrons (2008)
Presentation / Conference Contribution
Lenz, A. The theoretical status of B¯ − B-mixing and lifetimes of heavy hadrons

In this talk we review the theoretical status of the lifetime ratios of heavy hadrons and of the B-mixing quantities ΔMs, ΔΓs and φs. While ΔMs and ΔΓs suffer from large uncertainties due to the badly known decay constants, the ratio ΔΓs/ΔMs can be d...

Mixing and lifetimes of $b-$hadrons (2008)
Presentation / Conference Contribution
Lenz, A. J. (2008, July). Mixing and lifetimes of $b-$hadrons

We review the status of mixing and lifetimes of b‐hadrons. We will show that ΔΓ/ΔM, asl and φ are better suited to search for new physics effects than ΔM alone, because of our poor knowledge of the decay constants. The theoretical precision in the de...

Flavor changing neutral Higgs bosons in a supersymmetric extension based on a Q6 family symmetry. (2008)
Journal Article

A supersymmetric extension of the standard model based on the discrete Q6 family symmetry is considered, and we investigate flavor changing neutral current (FCNC) processes, especially those mediated by heavy flavor changing neutral Higgs bosons. Bec... Read More about Flavor changing neutral Higgs bosons in a supersymmetric extension based on a Q6 family symmetry..

Theoretical status of Bs-mixing and lifetimes of heavy hadrons (2008)
Presentation / Conference Contribution
Lenz, A., Castaldi, R., Chiarelli, G., Forti, F., & Scribano, A. (2008, March). Theoretical status of Bs-mixing and lifetimes of heavy hadrons. Presented at Hadron Collider Physics Symposium 2007., La Biodola, Isola d’Elba, Italy

We review the theoretical status of the lifetime ratios τB+/τBd, τBs/τBd, τΛb/τBd and τBc and of the mixing quantities ΔMs, ΔΓs and ϕs. ΔMs and ΔΓs suffer from large uncertainties due to the badly known decay constants, while the ratio ΔΓs/ΔMs can be... Read More about Theoretical status of Bs-mixing and lifetimes of heavy hadrons.
