Precision electroweak measurements on the Z resonance

2005

We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, $\MZ$ and $\GZ$, and its couplings to fermions, for example the $\rho$ parameter and the effective electroweak mixing angle, are precisely measured. The number of light neutrino species is determined to be 2.9840…

A multicentre prospective study of prostatic volume in asymptomatic men in various continents.

1997

Objective: To compare prostatic volumes in asymptomatic Asian men with similar controls in Europe. Patients and methods: Six centres (Beijing, Hong Kong, Jinan, Lisbon, Palermo and Stirling) independently selected asymptomatic men aged 55 y or more for assessment of prostatic volume using transrectal ultrasound (total=320 men) between 1992 and 1993. Results: Prostatic volumes in asymptomatic men were greater in Beijing than Hong Kong, Stirling and Palermo (P<0.05) and were smaller in Stirling than Beijing and Jinan (P<0.05). Conclusions: These results suggest that men from Stirling are less likely to have large prostates, but there is no evidence that men from any of the six cities are more…
