Flavor Tagging and Cp-violation Measurements at the Tevatron
The CDF collaboration has adapted several heavy flavor tagging techniques and employed them in analyses of time-dependent flavor asymmetries using data from the Tevatron Run I. The tagging algorithms were calibrated using low-Pt inclusive lepton and dilepton trigger data samples. The tagging techniques were applied to a sample of ∼ 400 B d /Bd → J/ψK 0 s decays and were used to measure the CP v...
متن کاملMixing and Cp -violation Measurements of B0 Mesons from the Tevatron Collider
B 0 mixing measurements from the Tevatron Run I data are reported. These include time-integrated measurements of the average mixing parameter , six time-dependent oscillation measurements of m d , and a time-dependent limit on m s. Such measurements provide constraints on CKM matrix elements. A sample of B 0 =B 0 ! J==K 0 S decays is used to directly measure the CP-violation parameter sin(2). T...
متن کاملMixing and CP -Violation Measurements of B Mesons from the Tevatron Collider
B mixing measurements from the Tevatron Run I data are reported. These include time-integrated measurements of the average mixing parameter χ, six timedependent oscillation measurements of ∆md, and a time-dependent limit on ∆ms. Such measurements provide constraints on CKM matrix elements. A sample of B/B → J/ψK S decays is used to directly measure the CP -violation parameter sin(2β). This valu...
متن کاملCP Violation , Top Quarks and the Tevatron Upgrade
In order to observe a signal of possible CP violation in top-quark couplings, we study top-quark production and decay under the conditions of the Tevatron upgrade. Transverse energy asymmetries sensitive to CP violation are defined. Applying the recently proposed optimal method, we calculate the statistical significance for the direct observation of CP violation in the production and subsequent...
متن کاملCP Violation in B Decays at the Tevatron
Between 1992 to 1996, the CDF and D0 detectors each collected data samples exceeding 100 pb−1 of pp̄ collisions at √ s = 1.8 TeV at the Fermilab Tevatron. These data sets led to a large number of precision measurements of the properties of B hadrons including lifetimes, masses, neutral B meson flavor oscillations, and relative branching fractions, and to the discovery of the Bc meson. Perhaps th...
