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.

TL;DR: In this article, a search for the neutral Higgs boson using the processes Z 0 → H 0 e + e −, Z0 → H ε + ε, Z ε → H τ + τ −, Zε → ε v v, and Z 0→ H 0 q q q, is performed on data collected by the ALEPH detector corresponding to about 11 550 events of Z0→ hadrons.

TL;DR: In this article, the authors measured the cross section for e + e − → hadrons over the center of mass energy range of the Z 0 peak, from 88.22 to 95.03 GeV.

TL;DR: In this article, the neutral Higgs boson produced in the decays of the Z 0 through the process Z 0 → H 0 l + l − in the mass range M H 0 0 → hadrons was excluded.

TL;DR: In this article, the forward-backward asymmetry in Z 0 → b b decays using hadronic events containing muons and electrons was measured using the single and dilepton p and P⊥ spectra.

TL;DR: In this article, the authors measured the cross-section of the reaction e + e − → γγ at center of mass energies around the Z 0 mass and found upper and lower bounds of 2.9 × 10 −4, 2.1×10 −4 and 1.2×10−4, respectively.

TL;DR: In this article, the authors search for excited electrons and muons from Z 0 decay in the channels ee→eeγ, ee →eeγγ, Ee→(e)eγ, (e)→μμγ, and Ee →μγγ using L3 detector at LEP.

TL;DR: In this article, the pair produced charged Higgs particles in the decays of Z0 were searched for the decay channels of H + H − →τ + ντ − ν, H + h − → τν cs and H + n − → c s c s.

TL;DR: In this paper, the excited electron neutrino produced from Z 0 decays in the channel e + e − →νν ∗ using the L3 detector at LEP.

TL;DR: In this paper, the authors measured the partial widths for the three reactions e + e − → Z 0 → e+ e −, μ + μ −, τ + τ −, and τ+ τ − data, the differential cross section as a function of polar angle for the electron data, and the forward-backward asymmetry for the muon data.
