The theoretical status of B¯ − B-mixing and lifetimes of heavy hadrons.

Lenz, Alexander (2008) 'The theoretical status of B¯ − B-mixing and lifetimes of heavy hadrons.', International journal of modern physics A., 23 (21). pp. 3321-3328.


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 determined with almost no non-perturbative uncertainties, therefore it can be used to look for possible new physics effects.
