Measurements of Parity-Violation Parameters at SLD
نویسنده
چکیده
We present direct measurements of the parity-violation parameters Ab, Ac, and As at the Z resonance with the SLD detector. The measurements are based on approximately 530k hadronic Z events collected in 1993-98. Obtained results are Ab = 0:914 0:024 (SLD combined: preliminary),Ac = 0:635 0:027 (SLD combined: preliminary), and As = 0:895 0:066(stat:) 0:062(sys:). Presented at the XXXth International Conference On High-Energy Physics (ICHEP 2000), 27 Jul 2 Aug 2000, Osaka, Japan Work supported by Department of Energy contract DE{AC03{76SF00515 (SLAC).

Measurements of Z to Heavy-quark couplings at SLD
We present measurements of Z to heavy-quark coupling electroweak parameters, Rb, Rc, and parity-violation parameter Ac, from SLD. The measurements are based on approximately 550k hadronic Z events collected in 1993-98. Obtained preliminary results of Rb and Rc measurements are Rb = 0:2159 0:0014 0:0014 and Rc = 0:1685 0:0047 0:0043. In the Ac measurement, we use four methods to determine the in...

SLC/SLD provides the ideal experimental environment to directly measure the parity violation parameters at the Zbb, Zcc vertex decays. Three di erent analysis techniques exploit the multi-purpose detector capabilities and are brie y described; the updated result obtained with the semileptonic decay method is presented. Presented at the 28th International Conference on High Energy Physics Warsaw...
متن کاملPole Using a Lepton Tag * the Sld Collaboration
The parity violation parameters A b and A c of the Zbb and Zc¯ c couplings have been measured directly, using the polar angle dependence of the polarized cross sections at the Z 0 pole. Bottom and charmed hadrons were tagged via their semileptonic decays. Both the electron and muon analyses take advantage of new multivariate techniques to increase the analyzing power. Based on the 1993-98 SLD s...

We present a new preliminary combination of measurements of the parity-violation parameter A b made by the SLD collaboration using various experimental techniques. The techniques differ in detail, but in general a sample of b ¯ b events is selected or enhanced by using the topologically reconstructed mass of the separated vertices formed by decaying B hadrons. The direction of the b(¯ b) quark ...
متن کاملConstraints on R–parity Violation from Precision Electroweak Measurements
Precision electroweak measurements provide a window to physics beyond the Standard Model by constraining the size of radiative corrections from new particles and interactions. In this contribution, we summarize the constraints from the LEP and SLD data on an R–parity violating extension to the MSSM. Details are presented in Ref. 1. We extend the MSSM with the addition of the the following terms...
