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. [...]

Electron and Positron Fluxes in Primary Cosmic Rays Measured with the Alpha Magnetic Spectrometer on the International Space Station / AMS Collaboration
Precision measurements by the Alpha Magnetic Spectrometer on the International Space Station of the primary cosmic-ray electron flux in the range 0.5 to 700 GeV and the positron flux in the range 0.5 to 500 GeV are presented. The electron flux and the positron flux each require a description beyond a single power-law spectrum. [...]

A precise measurement of the $W$-boson mass with the Collider Detector at Fermilab / Aaltonen, Timo Antero (Helsinki U. ; Helsinki Inst. of Phys.) ; Amerio, Silvia (INFN, Padua ; Padua U.) ; Amidei, Dante E (Michigan U.) ; Anastassov, Anton Iankov (Fermilab ; Northwestern U.) ; Annovi, Alberto (Frascati) ; Antos, Jaroslav (Comenius U. ; Kosice, IEF) ; Apollinari, Giorgio (Fermilab) ; Appel, Jeffrey A (Fermilab) ; Arisawa, Tetsuo (Waseda U.) ; Artikov, Akram Muzafarovich (Dubna, JINR) et al. /R. C. Group
We present a measurement of the $W$-boson mass, $M_W$, using data corresponding to 2.2/fb of integrated luminosity collected in ppbar collisions at $\sqrt{s}$ = 1.96 TeV with the CDF II detector at the Fermilab Tevatron. The selected sample of 470126 $W\to e\nu$ candidates and 624708 $W\to\mu\nu$ candidates yields the measurement $M_W = 80387\pm 12$ (stat) $\pm 15$ (syst)$ = 80387 \pm 19$ MeV$/c^2$ . [...]

Knowledge of the rigidity dependence of the boron to carbon flux ratio (B/C) is important in understanding the propagation of cosmic rays. The precise measurement of the B/C ratio from 1.9 GV to 2.6 TV, based on 2.3 million boron and 8.3 million carbon nuclei collected by AMS during the first 5 years of operation, is presented. [...]

A Study of the Energy Dependence of the Underlying Event in Proton-Antiproton Collisions / for the CDF Collaboration
We study charged particle production in proton-antiproton collisions at 300 GeV, 900 GeV, and 1.96 TeV. We use the direction of the charged particle with the largest transverse momentum in each event to define three regions of eta-phi space; toward, away, and transverse. [...]
