A Study of Cosmic Ray Secondaries Induced by the Mir Space Station Using AMS-01 / AMS Collaboration
The Alpha Magnetic Spectrometer (AMS-02) is a high energy particle physics experiment that will study cosmic rays in the $\sim 100 \mathrm{MeV}$ to $1 \mathrm{TeV}$ range and will be installed on the International Space Station (ISS) for at least 3 years. A first version of AMS-02, AMS-01, flew aboard the space shuttle \emph{Discovery} from June 2 to June 12, 1998, and collected $10^8$ cosmic ray triggers. [...]

Search for neutralino pair production at $\sqrt{s}$ = 189 GeV / DELPHI Collaboration
A search for pair-production of neutralinos at a LEP centre-of-mass energy of 189 GeV gave no evidence for a signal. This limits the neutralino production cross-section and excludes regions in the parameter space of the Minimal Supersymmetric Standard Model (MSSM)..

Measurement of the semileptonic b branching fractions and average b mixing parameter in Z decays / DELPHI Collaboration
The semileptonic branching fractions for primary and cascade b decays BR(b -> lepton-), BR(b -> c -> lepton+) and BR(b -> cbar -> lepton-) were measured in hadronic Z decays collected by the DELPHI experiment at LEP. The sample was enriched in b decays using the lifetime information and various techniques were used to separate leptons from direct or cascade b decays [...]

Update of the search for supersymmetric particles in scenarios with Gravitino LSP and Sleptons NLSP / DELPHI Collaboration
An update of the search for sleptons, neutralinos and charginos in the context of scenarios where the lightest supersymmetric particle is the gravitino and the next-to-lightest supersymmetric particle is a slepton, is presented, together with the update of the search for heavy stable charged particles in light gravitino scenarios and Minimal Supersymmetric Standard Models. Data collected in 1999 with the DELPHI detector at centre-of-mass energies around 192, 196, 200 and 202 GeV were analysed. [...]

Single Intermediate Vector Boson Production in $e^+ e^-$ collisions at $\sqrt{s}$ = 183 and 189 GeV / DELPHI Collaboration
The cross-sections for the production of single charged and neutral intermediate vector bosons were measured using integrated luminosities of 52~pb$^{-1}$ and 154~pb$^{-1}$ collected by the DELPHI experiment at centre-of-mass energies of 182.6~GeV and 188.6~GeV, respectively. The cross-sections for the reactions were determined in limited kinematic regions. [...]

Search for the Standard Model Higgs boson at LEP in the year 2000 / DELPHI Collaboration
Searches for the Standard Model Higgs boson have been performed in the data collected by the DELPHI experiment at LEP in the year 2000 at centre-of-mass energies between 200 and 209~\mbox{${\mathrm{GeV}} $} corresponding to a total integrated \mbox{luminosity} of 224~\mbox{pb$^{-1}$}. No evidence for a Higgs signal is observed in the kinematically accessible mass range, and a 95\% CL lower mass limit of 114.3~\mbox{${\mathrm{GeV}}/c ^2 $} is set, to be compared with an expected median limit of 113.5~\mbox{${\mathrm{GeV}}/c^2 $} for these data..

A Measurement of the Tau Topological Branching Ratios / DELPHI Collaboration
Using data collected in the DELPHI detector at LEP-1, measurements of the inclusive tau branching ratios for decay modes containing one, three, or five charged particles have been performed, giving the following results: B_1 = B(\tau^- -> (particle)^- \geq 0pi^0 \geq 0K^0 \nu_\tau(\bar{\nu})) = (85.316 +/- 0.093 +/- 0.049)%; B_3 = B(\tau^- -> 2h^-h^+ \geq 0pi^0 \geq 0K^0 \nu_\tau) = (14.569 +/- 0.093 +/- 0.048)%; B_5 = B(\tau^- -> 3h^-2h^+ \geq 0pi^0 \geq 0K^0 \nu_\tau) = (0.115 +/- 0.013 +/- 0.006)%, where h is either a charged pi or K meson. The first quoted uncertainties are statistical and the second systematic..
