Lifetimes of b-flavoured hadrons
I discuss the heavy quark expansion for the inclusive widths of heavy-light hadrons, which predicts quite well the experimental ratios of Bq meson lifetimes. As for Λb, current determinations of O(m−3 b ) contribution to τ(Λb) do not allow to explain the small measured value of τ(Λb)/τ(Bd). As a final topic, I discuss the implications of the measurement of the Bc lifetime. 1. Lifetimes of heavy...
متن کاملLifetimes of Heavy Hadrons *
We review current status of theoretical predictions of lifetimes of heavy hadrons in heavy-quark expansion. We present a calculation of subleading 1/m b corrections to spectator effects in the ratios of beauty hadron lifetimes. We find that these effects are sizable and should be taken into account in systematic analyses of heavy hadron lifetimes. In particular, the inclusion of 1/m b correctio...
متن کاملPrecision physics with heavy-flavoured hadrons
The understanding of flavour dynamics is one of the key aims of elementary particle physics. The last 15 years have witnessed the triumph of the Kobayashi-Maskawa mechanism, which describes all flavour changing transitions of quarks in the Standard Model. This important milestone has been reached owing to a series of experiments, in particular to those operating at the so-called B factories, at...
متن کاملProperties of Heavy Flavoured Hadrons at CDF
We present recent CDF results on the properties of hadrons containing heavy quarks. These include the measurements of mass, lifetime and relative cross section of the B c meson and an updated measurement of the B 0 s and Λ 0 b lifetime. We also summarize new measurements of the mass of the Σ b baryon.
متن کاملMasses and Lifetimes of B Hadrons
The latest measurements of the masses and lifetimes of weakly decaying B hadrons from experiments at ee and pp̄ colliders are presented. These measurements include the lifetimes of the B̄, B̄ s , B , and b baryons, as well as searches for the Bc meson. The observation of B, p-wave B mesons (B), and excited b baryons using inclusive and exclusive B hadron reconstruction are discussed. Results on b ...
