Inclusive Search for b!sg y The SLD Collaboration
ثبت نشده
چکیده
We describe an inclusive search for avor changing neutral current decays of the type b!s gluon in the SLD experiment. Models of b!sg indicate that the production of high momentum kaons is enhanced over background from standard B decays. If the branching ratio for b!sg is 10, then such an enhancement should have a goodsignal to background ratio. The analysis makes use of the particle identiication and high precision vertexing capabilities of SLD to search for such an enhancement. The data sample consists of 300K hadronic Z 0 decays collected between 1993 and 1997.

Decay Studies at SLD ∗
We present three preliminary results from SLD on B decays: an inclusive search for the process b → s gluon, a measurement of the branching ratio for the process B → D ¯ DX, and measurements of the charged and neutral B lifetimes. All three measurements make use of the excellent vertexing efficiency and resolution of the CCD Vertex Detector and the first two make use of the excellent particle id...

Representing the SLD collaboration We present measurements of identified charged hadron production over a wide momentum range using the SLD Cherenkov Ring Imaging Detector. In addition to studying particle production in flavor-inclusive Z 0 decays, we compare the production in decays into light, c and b flavor events. We also examine particle production in gluon jets with that in light quark je...

Results on heavy quark fragmentation obtained using the SLD detector at the SLAC Linear Collider are presented. This talk will cover the ratio of vector to pseudoscalar charmed meson production, the inclusive B hadron energy distribution, the inclusive particle production in heavy jets compared to their production in light jets, and charged and neutral B meson lifetimes.
متن کاملMeasurement of a C with Charmed Mesons at Sld * the Sld Collaboration
We present a direct measurement of the parity-violation parameter A c. The measurement is based on 550k Z 0 decays collected by the SLD detector. The mean electron-beam polarization is |P e | = 73%. The tagging of c-quark events was performed using two methods: The exclusive reconstruction of D * + , D + , and D 0 mesons, and the inclusive P T spectrum of soft-pions (π s) in the decay of D * + ...
متن کاملRepresenting The SLD Collaboration
We report new preliminary B Physics results obtained with 300,000 hadronic Z decays collected by the SLD experiment at the SLC between 1993 and 1997. Three analyses are presented: a measurement of B and B d lifetimes, a study of the time dependence of B s–B 0 s mixing, and a search for decays of the type b → s g. All analyses benefit from the small and stable interaction point and the excellent...
