AbstractAbstract
[en] The latest results for the measurement of the CP violating phase βs in Bs0 → J/Ψφ decays, from 5.2 fb-1 integrated luminosity of CDF data are presented. For the first time, this measurement includes the contribution of Bs0 → J/ΨK+K- or Bs0 → J/Ψf0 events to the signal sample, where the f0 and non-resonant K+K- are S-wave states. Additional improvements to the analysis include more than doubling the signal sample, improved selection and particle ID, and fully calibrated flavour tagging for the full dataset. Additionally, the world's most precise single measurements of the Bs0 lifetime, τs, and width difference, ΔΓs are given.

AbstractAbstract
[en] While B0 and B+ mesons are well studied, mainly by the B factories, less is known about Bs mesons. Specifically large new physics effects may still be present in the Bs system. This unexplored region is studied by the CDF, D0, and Belle experiments. In this article their recent measurements on the Bs physics sector are presented.

AbstractAbstract
[en] Recently, the B factory experiments BABAR and Belle as well as the CDF collaboration found evidence for mixing in the D meson system. The current status (beginning of summer 2008) of the experimental results of D0 mixing is summarized. In this paper, we present an overview of D0 mixing. After an introduction to the charm mixing phenomenology and analysis techniques, results of the mixing parameters and CP violation as related to mixing are summarized. They are obtained from hadronic two-body, multi-body final states and from quantum correlated D0 decays of the experiments BABAR, Belle, Cleo and CDF. Mixing results from semileptonic D0 decays can be found elsewhere.

AbstractAbstract
[en] We describe the CDF Central Outer Tracker (COT), an open-cell drift chamber currently being constructed for the CDF detector to run at the upgraded Fermilab Tevatron collider. This detector will provide central tracking with excellent momentum resolution in the high- density environment of a hadron collider. It will be able to resolve 132 ns beam crossings and provide tracking trigger information to the Level 1 trigger. The design is based upon the existing and successful CDF Central Tracking Chamber. The preliminary mechanical and electrical designs are presented. 5 refs., 5 figs., 1 tab

AbstractAbstract
[en] Detailed calculations of the accelerator related background in the CDF forward muon spectrometer have been performed with the MARS13 code and a newly developed C++ code for particle tracking in accelerator lattices. Calculated space distributions of background hits are in a good agreement with data taken in Run I. Several shielding configurations in the CDF hall and Tevatron tunnel have been studied. The optimal one provides a 30-fold shielding efficiency compatible with CDF Run II requirements

AbstractAbstract
[en] The authors present a measurement of the Bs0 lifetime in fully and partially reconstructed Bs0 → Ds0(φπ-)X decays in 1.3 fb-1 collected in p(bar p) collisions at √s = 1.96 Tev by the CDF II detector at the Fermilab Tevatron. They measure τ(Bs0) = 1.518 ± 0.041 (stat.) ± 0.027 (syst.) ps. The ratio of this result and the world average B0 lifetime yields τ(Bs0)/τ(B0) = 0.99 ± 0.03, which is in agreement with recent theoretical predictions.

AbstractAbstract
[en] In this paper we describe the detector components, triggers and analysis techniques for flavor physics at the Tevatron experiments CDF and D0. As Tevatron performs very well and runs at higher luminosities regularly we also touch issues related to it and efforts to improve detectors and triggers for such running.

AbstractAbstract
[en] Last month's edition (April, page 12) included a status report on data collection and preliminary physics results from the 'newcomer' DO detector at Fermilab's Tevatron proton-antiproton collider. This time the spotlight falls in the Veteran' CDF detector, in action since 1985 and meanwhile significantly upgraded. Meanwhile the Tevatron collider continues to improve, with record collision rates
