Determination of the number of light neutrino species

O. Adriani, +496 more
- 15 Oct 1992 - 
TL;DR: In this paper, the number of light neutrino species is found to be Nv=3.30% CL with the constraints of the standard electroweak model, which rules out the possibility of a fourth type of LN at 98% CL.
Journal ArticleDOI

The L3 silicon microvertex detector

M. Acciarri, +101 more
TL;DR: In this article, the design and construction of the silicon strip microvertex detector (SMD) of the L3 experiment at LEP are described and the sensors, readout electronics, data acquisition system, mechanical assembly and support, displacement monitoring systems and radiation monitoring system of the recently installed double-sided, double-layered SMD.
Journal ArticleDOI

A determination of the properties of the neutral intermediate vector boson Z0

Bernardo Adeva, +454 more
- 16 Nov 1989 - 
TL;DR: The first physics runs of the L3 detector at LEP were reported in this article, where the authors determined the mass m z 0 and the width Γ z 0 of the intermediate vector boson Z 0 to bem z 0 =91.132±0.057 GeV (not including the 46 MeV LEP machine energy uncertainty).

Search for Isosinglet Neutral Heavy-Leptons in Z0 Decays

O. Adriani, +512 more
- 03 Dec 1992 - 
TL;DR: In this paper, neutral heavy leptons that are isosinglets under the standard SU (2)L gauge group were searched for and no evidence for a signal has been found and the limit Br(NSu0 → vlNl) < 3 x 10−5 at the 95% CL for mass range from 3 GeV up to Mz.
