Parallel Talk

Using the Unitarity Triangle analysis, generalized to account the presence of physics beyond the Standard Model, we discuss the current model-independent bounds on New Physics contributions to K-Kbar, D-Dbar and Bq-Bqbar (q=d,s) mixing processes. This information is then translated into a lower limit on the probed scale of New Physics. We consider several scenarios, such as a New...

Parallel Talk

We present measurements of the three Bs mixing parameters: the mass and width difference between the heavy and light mass eigenstates, Delta M_s and Delta Gamma_s respectively, and the CP violating phase difference between Delta M_s and Delta Gamma_s, phi_s. The results are based on a large data set of proton-antiproton collisions recorded by the Dzero detector operating at the...

We report on the progress of the analysis of $B0_s \to J/\psi \phi$ decays to extract the parameters $\Delta \Gamma_s / \Gamma_s$ and $\sin 2 \beta_s$ with the CDF\,II detector. The use of a time-dependent angular analysis can separate the $CP$~eigenstates of the $B0_s$~meson to determine their separate lifetimes. Further tagging of the $B0_s$ meson at time $t=0$ as $B0_s$ or...

Parallel Talk

The LHC experiments will perform sensitive tests of physics phenomena beyond the Standard Model (BSM). Investigation of decays of beauty hadrons represents an alternative approach in addition to direct BSM searches. The ATLAS and CMS efforts concentrate on those B decays that can be selected already at the first and second trigger levels. The most favorable trigger signature will be...

388. Time-dependent CP asymmetries in Bs decays at LHCb

Parallel Talk

The LHCb experiment will search for New Physics in Bs mixing, notably through the measurement of the Bs mixing phase from the time-dependent CP asymmetry in exclusive Bs decays governed by the b ->ccbar s quark-level transition. Large New Physics effects can be discovered or excluded with the data collected during the very first physics run of LHC. The latest expectations, based on MC ...

237. Prospects for a high-luminosity Super B Factory

Parallel Talk

Conceptual designs for very high luminosity asymmetric energy e+e- flavor factories have been advanced by a group centered at KEK (Super KEKB) and by an international collaboration sponsored by INFN Italy (SuperB). These facilities would provide up to a factor of 100 larger data samples than available from the current round of B Factories at SLAC and KEK. The primary physics motivation for...
