B Mixing and Lifetimes at the Tevatron
نویسندگان
چکیده
The Tevatron collider at Fermilab, operating at √ s = 1.96 TeV, has a huge bb̄ production cross section which is several orders of magnitude larger than the production rate at ee colliders running on the Υ(4S) resonance. In addition, on the Υ(4S) only B and B d are produced, while higher mass b-hadrons such as B s , Bc, b-baryons, B , and p-wave B mesons are currently produced only at the Tevatron. Both DØ and CDF II are multipurpose detectors featuring high resolution tracking in a magnetic field and lepton identification. These detectors are symmetrical in polar and azimuthal angles around the interaction point, with approximate 4π coverage [1, 2]. The CDF II and DØ detectors are able to trigger at the hardware level on large track impact parameters, enhancing the potential of their B physics programs.

B Lifetimes and Mixing
The Tevatron experiments, CDF and D0, have produced a wealth of new B-physics results since the start of Run II in 2001. We’ve observed new B-hadrons, seen new effects, and increased many-fold the precision with which we know the properties of b-quark systems. In these proceedings, we will discuss two of the most fruitful areas in the Tevatron B-physics program: lifetimes and mixing. We’ll exam...
متن کاملMixings, Lifetimes, Spectroscopy and Production of Heavy Flavor at the Tevatron
In the 1980’s and 1990’s, the complementary b physics programs of CLEO, ARGUS, the LEP experiments, SLD, DØ and CDF began to make significant contributions to our understanding of the production and decay of B hadrons. With the successful turnon of the BaBar and Belle experiments in the last few years, many experimental measurements in the b sector have achieved impressive precision. A number o...
متن کاملRecent Lifetime and Mixing Measurements at the Tevatron
We present the latest B hadron lifetimes, B s mixing, and D 0 mixing measurements using up to 3.0 fb of data collected by CDF and D0 experiments at Fermilab. The B s lifetime is measured from both J/ψφ (CP admixture) and flavor specific channels, and the Bc lifetime is obtained from semileptonic channels. Following the B s oscillation frequency measurement at CDF in 2006, the D0 collaboration n...
متن کاملCp Violation, Mixing and Rare Decays at the Tevatron Now and in Run Ii I Introduction
We review the status of current B mixing and CP violation measurements from the Fermilab Tevatron. With the existing data sample, the CDF collaboration has made competitive measurements of B 0 d mixing; set limits on B 0 s mixing; and has begun a direct search for CP violation in the B system through the decay B 0 =B 0 ! J==K 0 s. The prospects for future b measurements at the Tevatron, includi...
