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.

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).

TL;DR: In a search for the Standard Model Higgs boson, carried out on 212.5~$\mathrm{pb^{-1}}$ above $\sqrt{s} = 206$~GeV, an excess of candidates for the process was found for Higgs masses near 114.5 ~GeV as mentioned in this paper.

TL;DR: In this article, the formation of the η′ in the reaction e+e−→e+e −η−η′→e−π+π−γ has been measured by the L3 detector at a centre-of-mass energy of 91 GeV.

TL;DR: In this article, it is shown that the goal of space valorization cannot be considered without relational investment between the partners and their accumulated background, and that the capacity of the territory to solve these problems will depend closely on the richness of the network and co-operations which it shelters or it will suggest.
