Measurement of the Left - Right Cross Section Asymmetry in Z Boson Production

A Precise Measurement of the Left-Right Cross Section Asymmetry in Z Boson Production

This thesis presents a measurement of the left-right asymmetry, ALR, in the production cross section of Z Bosons produced by e+eannihilations, using polarized electrons, at a center of mass energy of 91.26 Gev. The data presented was recorded by the SLD detector at the SLAC Linear Collider during the 1993 run. The mean luminosity-weighted polarization of the electron beam was plutn = (63.0 i 1....

Lepton-flavor-violating decays of the Z boson in a left-right supersymmetric model.

We study the one-loop supersymmetric contributions to lepton-flavor violating Z -boson decays in a fully left-right symmetric model. In addition to right-handed scalar neutrinos, the decays could receive important contributions from doubly-charged triplet Higgsinos which couple to leptons only. We find that the decay widths reach present experimental bounds and discuss mass constraints for the ...

Measurement of the Left-Right Cross Section Asymmetry in Z Boson Production in ee Collisions

A precise measurement of the left-right cross section asymmetry (ALR) for Z boson production by ee collisions has been performed at the SLAC Linear Collider with the SLD detector. Data for the 1993 run, with its signi cant improvements in luminosity and electron beam polarization, are presented. When combined with the (less precise) 1992 result, the preliminary result for the e ective weak mixi...

Alzheimer's disease amyloid beta converting left-handed Z-DNA back to right-handed B-form.

Herein we report that Aβ aggregates, not Aβ monomer, can convert Z-DNA back to B-form, and curcumin, a well-known Aβ aggregation inhibitor, can stop DNA Z-B transition studied by means of biophysical and biochemical methods.
