TL;DR: In this paper, the performance of the muon reconstruction in the analysis of proton-proton collisions at the LHC was studied in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons.

- 12 Dec 1996 - 
TL;DR: In this paper, an upper limit for BR(Z0 → 3g) was obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions.

A search for invisible Higgs bosons produced in e+ e- interactions up to s**(1/2) = 189-GeV

TL;DR: In this article, the DELPHI results were combined with the results of the Hadronic and muon pair final states of the hadronic and hadronic pair of the d {\mbox{$ {\mathrm Z} $}} d boson to obtain a 95% confidence level upper bound on the cross-section and the corresponding Higgs boson mass lower limit.
