CP 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...
متن کاملFlavor 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 کاملStudies of CP Violation at BABAR
BABAR has studied the time dependent asymmetries in the the decays B → J/ψK S and B → ψ(2S)K S in a data set of 9.0 fb taken at the Υ (4S) resonance. In these channels we reconstruct 168 events of which 120 are flavor tagged and used in a likelihood fit where we determine sin 2β. The flavor of the other neutral B mesons is tagged using information primarily from identified leptons and Kaons. A ...
متن کاملCP-violating Higgs at Tevatron
We analyze the prospect for observing the intermediate neutral Higgs (h2) boson in its decay to two lighter Higgs bosons (h1) at the Tevatron in the framework of the CP violating MSSM using the PYTHIA event generator. We consider the lepton+ 4-jets+ E/T channel from pp̄ → W h2 → W h1h1 → lνlbb̄bb̄, with two or three tagged b jets. We found that it is very hard to observe this signature in the LEP-...
متن کاملRare B Decays, Mixing and Cp Violation at Tevatron (rare B Decays and Observation of B + C Mesons at Tevatron)
a We report the results of the search for avor changing-neutral current (FCNC) decays b ! ss + ? and the observation of B + c mesons at Tevatron. 1 Search for the avor-changing neutral-current decays b ! ss + ? The avor-changing neutral-current (FCNC) decays b ! s` + ` ? are forbidden at the tree level diagram. They can proceed through the higher order diagrams, i.e., penguin and box diagrams w...
