    “PI OF THE SKY” OFF-LINE EXPERIMENT WITH GLORIA

    Get PDF
    GLORIA is the first free and open-access network of robotic telescopes in the world. Based on the Web 2.0 environment, amateur and professional users can do research in astronomy by observing with robotic telescope, and/or analyzing data acquired with GLORIA, or from other free access databases. The GLORIA project develops free standards, protocols and tools for controlling Robotic Telescopes and related instrumentation, for scheduling observations in the telescope network, and for conducting so-called off-line experiments based on the analysis of astronomical data. This contribution summarizes the implementation and results from the first research level off-line demonstrator experiment implemented in GLORIA, which was based on data collected with the “Pi of the Sky” telescope in Chile

    Focus topics for the ECFA study on Higgs / Top / EW factories

    Full text link
    In order to stimulate new engagement and trigger some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an e+ee^+e^- Higgs / Top / Electroweak factory, we propose to define a set of focus topics. The general reasoning and the proposed topics are described in this document.Comment: v3: fixed spelling of two author

    The azimuthal correlation angle, Δϕ\Delta\phi, between the scattered lepton and the leading jet in deep inelastic e±pe^{\pm}p scattering at HERA has been studied using data collected with the ZEUS detector at a centre-of-mass energy of s=318  GeV\sqrt{s} = 318 \;\mathrm{GeV}, corresponding to an integrated luminosity of 326  pb1326 \;\mathrm{pb}^{-1}. A measurement of jet cross sections in the laboratory frame was made in a fiducial region corresponding to photon virtuality 10  GeV210  GeV10 \;\mathrm{GeV}^2 10 \;\mathrm{GeV}, lepton polar angle 140<θe<180140^\circ < \theta_e < 180^\circ, jet transverse momentum 2.5  GeV<pT,jet<30  GeV2.5 \;\mathrm{GeV} < p_\mathrm{T,jet} < 30 \;\mathrm{GeV}, and jet pseudorapidity 1.5<ηjet<1.8-1.5 < \eta_\mathrm{jet} < 1.8. Jets were reconstructed using the kTk_\mathrm{T} algorithm with the radius parameter R=1R = 1. The leading jet in an event is defined as the jet that carries the highest pT,jetp_\mathrm{T,jet}. Differential cross sections, dσ/dΔϕd\sigma/d\Delta\phi, were measured as a function of the azimuthal correlation angle in various ranges of leading-jet transverse momentum, photon virtuality and jet multiplicity. Perturbative calculations at O(αs2)\mathcal{O}(\alpha_{s}^2) accuracy successfully describe the data within the fiducial region, although a lower level of agreement is observed near Δϕπ\Delta\phi \rightarrow \pi for events with high jet multiplicity, due to limitations of the perturbative approach in describing soft phenomena in QCD. The data are equally well described by Monte Carlo predictions that supplement leading-order matrix elements with parton showering
