    In this paper selected results obtained by the ALICE experiment at the LHC will be presented. Data collected during the pp runs taken at sqrt(s)=0.9, 2.76 and 7 TeV and Pb-Pb runs at sqrt(s_NN)=2.76 TeV allowed interesting studies on the properties of the hadronic and nuclear matter: proton runs gave us the possibility to explore the ordinary matter at very high energy and up to very low pt, while Pb-Pb runs provided spectacular events where several thousands of particles produced in the interaction revealed how a very dense medium behaves, providing a deeper picture on the quark gluon plasma(QGP) chemical composition and dynamics.Comment: Proceeding of the Conference "New Trends in High Energy Physics", Alushta, Crimea, Ukraine, September 3 - 10, 201

    We present first results about the measurement of the charged hadrons production by atmopsheric muons in the rock above MACRO. A comparison between the measure rate with the Monte Carlo expectation is presentedComment: 4 pages, 2 figures, to be published in Proc. of Xth ISVHECR

    Results on ultra-peripheral interactions in Pb-Pb and p-Pb collisions in ALICE

    Full text link
    Ultra-relativistic heavy ions generate strong electromagnetic fields which offer the possibility to study γ\gamma-nucleus and γ\gamma-proton interactions at the LHC in the so called ultra-peripheral collisions (UPC). Here we report ALICE results on J/psi photoproduction measured in Pb-Pb collisions at sNN\sqrt{s_{\rm NN}} = 2.76 TeV and in p-Pb collisions at sNN\sqrt{s_{\rm NN}} = 5.02 TeV.Comment: Presented at EDS Blois 2013 (arXiv:1309.5705

    Study of neutrino induced upgoing muon energy

    Get PDF
    An estimate of the energy of neutrino-induced muons in MACRO is provided by a multiple Coulomb scattering measurement. The MACRO original upward-muon data sample has been subdivided according to the reconstructed muon energy. The results are interpreted in terms of neutrino oscillation

    Il problema della temporalità nella filosofia di Edmund Husserl

    Get PDF
    La fondazione della logica e la tematizzazione dell'intenzionalità come vivificazione di un contenuto inerte. Insufficienza di una tale spiegazione e conseguente approfondimento della dimensione temporale della coscienza. L'abbandono dello schema apprensione-contenuto d'apprensione. Il flusso assoluto costitutivo di tempo come intenzionalità originari

    Performance of a large limited streamer tube cell in drift mode

    Get PDF
    The performance of a large (3x3 cm2cm^2) streamer tube cell in drift mode is shown. The detector space resolution has been studied using cosmic muons crossing an high precision silicon telescope. The experimental results are compared with a GARFIELD simulation.Comment: 18 pages, 7 figures. Accepted by Nucl. Instr. and Methods
