چکیده
We present the measurements of the leptonic asymmetries in Z decays measured by the SLD experiment at SLAC. A data sample of approximately 550,000 Z bosons are used for the preliminary measurement of ALR(Ae) and the leptonic final state measurements of Ae, Aμ and Aτ , representing the entire set of 1992-1998 SLD runs. When combining all results, a preliminary value for the effective weak mixing angle is obtained: sinθ W = 0.23109 ± 0.00029. We also present the direct measurements of Ab from left-right forward-backward asymmetries, using partial data samples from 1993-1998 SLD runs. The preliminary value combines jet charge, cascade kaon and semileptonic decay analyses to obtain Ab = 0.866± 0.036.

This paper presents measurements of the leptonic asymmetries in Z decays measured with the SLD detector. Using a data sample of approximately 500,000 Z bosons, we report preliminary values for Ae, Aμ, and Aτ using both hadronic and leptonic decays. When combining all results, we report a preliminary value for the effective weak mixing angle sin θ W = 0.23110± 0.00029. Presented at the XXIX Inte...

We give an analytic formula for the double distribution of hadronic invariant mass and charged lepton energy to one-loop order of the perturbative QCD. Although infrared singular, this quantity is closely related to physical observables that can be obtained thereof through proper convolution.

Complementary measurements have been performed for the level density and γ strength function in 162 Dy using inelastic 3 He scattering. Comparing these results to previous measurements using the 163 Dy(3 He,α) reaction , reveals that the measured quantities above 1.5 MeV do not depend significantly on the nuclear reaction chosen.

The Beijing Spectrometer, BES, is a conventional cylindrical magnetic detector that is coaxial with the BEPC colliding e+e− beams. It is described in detail in Ref. [1]. A four-layer central drift chamber (CDC) surrounding the beampipe provides trigger information. Outside the CDC, the forty-layer main drift chamber (MDC) provides tracking and energy-loss (dE/dx) information on charged tracks o...
