TL;DR: This paper presents national plans on referencing and archiving doctoral theses coordinated by the government as well as some initiatives for creating full text archives.

TL;DR: In this paper, the authors search for lepton flavour violation in Z boson decays into lepton pairs using all data collected with the L3 detector during the 1990, 1991 and 1992 runs on an event sample corresponding to 1 500 000 Z's produced.

TL;DR: In this article, the authors report on inclusive xc production in Z decays reconstructed via the decay mode Xc → J + γ using 1.1 million hadronic Z events and obtain a branching ratio Br(Z→ Xcl + X) = (7.5±2.9(stat.) ± 0.6(sys.)) × 10−3.

TL;DR: In this paper, the search for the electromagnetic penguin decay b → sγ at √s ≈ mz was conducted and no evidence for a signal was found and an upper limit on the decay rate Br(b→ sγ) < 1.2 × 10−3 at 90% C.L.

TL;DR: The average lifetime ofB hadrons has been measured by the TASSO collaboration using 110 pb−1 of data collected in 1986 at a center of mass energy of 35 GeV using three different methods and a method ofB-enrichment is discussed.
