[en] The latest results for the measurement of the CP violating phase β_s in B_s⁰ → 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 B_s⁰ → J/ΨK⁺K^- or B_s⁰ → 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 B_s⁰ lifetime, τ_s, and width difference, ΔΓ_s are given.

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

[en] The authors present a measurement of the B_s⁰ lifetime in fully and partially reconstructed B_s⁰ → D_s⁰(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(B_s⁰) = 1.518 ± 0.041 (stat.) ± 0.027 (syst.) ps. The ratio of this result and the world average B⁰ lifetime yields τ(B_s⁰)/τ(B⁰) = 0.99 ± 0.03, which is in agreement with recent theoretical predictions.

[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.

[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

[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

[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.

[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

[en] We present results from direct searches for leptoquarks and R-parity violating SUSY particles by the CDF experiment. These results strongly constrain the interpretation of the recently reported high Q² event excess at HERA as leptoquark or R-parity violating SUSY production
