Extracting Rb and Rc without flavor tagging.
At present, two outstanding discrepancies between experiment and the standard model are the measurements of the hadronic branching fractions Rb and Rc. We note that an independent measurement of these branching fractions may be obtained from the width of hadronic Z decays with a prompt photon, Γqq̄γ, along with the total hadronic decay rate, Γhad, and an additional theoretical assumption. Such a...
متن کاملQuark flavor tagging in polarized hadronic processes
We describe a general approach to quark flavor tagging in polarized hadronic processes, with particular emphasis on semi-inclusive deep inelastic scattering. A formalism is introduced that allows one to relate chosen quark flavor polarizations to an arbitrary combination of final-state hadron asymmetries. Within the context of the presented formalism, we quantify the sensitivity of various semi...

متن کاملMethod for flavor tagging in neutral B meson decays.
So far, CP violation has been seen only in decays of neutral kaons. The leading contender for description of this effect, a non-trivial phase in the Cabibbo-KobayashiMaskawa (CKM) matrix [1], makes specific predictions for CP-violating asymmetries in decays of mesons containing a b quark. These asymmetries are particularly easily interpreted in decays of neutral B mesons to CP eigenstates such ...
متن کاملFlavor Tagging at Tevatron Incl. Calibration and Control
This report summarizes the flavor tagging techniques developed at the CDF and DØ experiments. Flavor tagging involves identification of the B meson flavor at production, whether its constituent is a quark or an anti-quark. It is crucial for measuring the oscillation frequency of neutral B mesons, both in the B 0 and B 0 s system. The two experiments have developed their unique approaches to fla...
