A measurement of the cosmic ray positron fraction e+/(e++e−) in energy range 1–30 GeV is presented. The based on data taken by AMS-01 experiment during its 10 day Space Shuttle flight June 1998. proton background suppression order 106 reached identifying converted bremsstrahlung photons emitted from positrons.
A small electromagnetic sampling calorimeter, installed in the ZEUS experiment 1995, significantly enhanced acceptance for very low x and Q^2 inelastic neutral current scattering, e^{+}p \to e^{+}X, at HERA. measurement of proton structure function F_2 total virtual photon-proton (\gamma^*p) cross-section is presented 0.11 \le Q^{2} 0.65 GeV^2 2 \times 10^{-6} 6 10^{-5}, corresponding to a range \gamma^{*}p c.m. energy 100 W 230 GeV. Comparisons with various models are also presented.
The photoproduction reaction gamma p -> mu+ mu- has been studied in ep interactions using the ZEUS detector at HERA. data sample corresponds to an integrated luminosity of 43.2 pb^{-1}. Upsilon meson observed for first time. sum products elastic Upsilon(1S), Upsilon(2S), Upsilon(3S) cross sections with their respective branching ratios is determined be 13.3 +- 6.0(stat.)^{+2.7}_{-2.3}(syst.) pb a mean photon-proton centre mass energy 120 GeV. section above prediction perturbative QCD model.
This paper presents measurements of D∗± production in deep inelastic scattering from collisions between 27.5 GeV positrons and 820 protons.

We present an analysis of muon events with all multiplicities collected during 21804 h operation the first Large Volume Detector tower. The measured angular distribution intensity has been converted to "depth–vertical-intensity" relation in depth range from 3 12 km w.e. this allowed us derive power index γ primary all-nucleon spectrum: γ=2.78±0.05. standard rock and comparison data other experiments done. also derived vertical spectrum at sea level.Received April...
A search for single-top production, ep --> etX, has been made with the ZEUS detector at HERA using an integrated luminosity of 130.1 pb-1. Events from both leptonic and hadronic decay channels W boson resulting top quark were sought. For mode, was events isolated high-energy leptons significant missing transverse momentum. three-jet in which two jets had invariant mass consistent that selected. No evidence production found. The results are used to constrain via flavour-changing neutral...
The HERA electron--proton collider has collected 100 pb$^{-1}$ of data since its start-up in 1992, and recently moved into a high-luminosity operation mode, with upgraded detectors, aiming to increase the total integrated luminosity per experiment more than 500 pb$^{-1}$. been machine excellence for study QCD structure proton. Large Hadron Collider (LHC), which will collide protons centre-of-mass energy 14 TeV, be completed at CERN 2007. main mission LHC is discover mechanisms electroweak...
Measurement of the chemical and isotopic composition cosmic rays is essential for precise understanding their propagation in galaxy. While model parameters are mainly determined using B/C ratio, study extended sets ratios can provide stronger constraints on models. In this paper, relative abundances light-nuclei lithium, beryllium, boron, carbon presented. The secondary-to-primary Li/C, Be/C, have been measured kinetic energy range 0.35–45 GeV nucleon−1. ratio 7Li/6Li also magnetic rigidity...
