First Result from the Alpha Magnetic Spectrometer on the International Space Station: Precision Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5–350 GeV / AMS Collaboration
A precision measurement by the Alpha Magnetic Spectrometer on the International Space Station of the positron fraction in primary cosmic rays in the energy range from 0.5 to 350 GeV based on 6.8×106 positron and electron events is presented. The very accurate data show that the positron fraction is steadily increasing from 10 to ∼250  GeV, but, from 20 to 250 GeV, the slope decreases by an order of magnitude. [...]

The Alpha Magnetic Spectrometer (AMS) on the International Space Station. I: Results from the test flight on the space shuttle / AMS Collaboration
The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 (June 1998) in a 51.7° orbit at altitudes between 320 and 390 km . A search for antihelium nuclei in the rigidity range 1– 140 GV was performed. [...]

Isotopic Composition of Light Nuclei in Cosmic Rays: Results from AMS-01 / AMS-01 Collaboration
The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper, we present measurements of the isotopic ratios $^2$H/$^4$He, $^3$He/$^4$He, $^6$Li/$7$Li, $7$Be/($^9$Be+$^{10}$Be), and $^{10}$B/$^{11}$B in the range 0.2-1.4 GeV of kinetic energy per nucleon. [...]

Relative Composition and Energy Spectra of Light Nuclei in Cosmic Rays. Results from AMS-01 / AMS-01 Collaboration
Measurement of the chemical and isotopic composition of cosmic rays is essential for the precise understanding of their propagation in the galaxy. While the model parameters are mainly determined using the B/C ratio, the study of extended sets of ratios can provide stronger constraints on the propagation models. [...]

Cosmic-ray positron fraction measurement from 1 to 30 GeV with AMS-01 / AMS-01 Collaboration
A measurement of the cosmic ray positron fraction e+/(e+ + e-) in the energy range of 1-30 GeV is presented. The measurement is based on data taken by the AMS-01 experiment during its 10 day Space Shuttle flight in June 1998. [...]

Charge determination of nuclei with the AMS-02 silicon tracker / Alpat, B ; Ambrosi, G ; Azzarello, P ; Battiston, R ; Bene, P ; Bertucci, B ; Bizzaglia, S ; Bizzarri, M ; Blasko, S ; Bourquin, M et al.
The silicon tracker of the AMS-02 detector measures the trajectory in three dimensions of electrons, protons and nuclei to high precision in a dipole magnetic field and thus measures their rigidity (momentum over charge) and the sign of their charge. In addition, it measures the specific energy loss of charged particles to determine the charge magnitude. [...]

Precision electroweak measurements on the $Z$ resonance / ALEPH Collaboration
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. [...]

Results on the hadronic final state in e/sup +/e/sup -/ annihilation at 13, 17 and 27.4 GeV are presented. There is no compelling evidence for the existence of the t quark in these data, which are in general agreement with a simple quark parton model. [...]
