    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

    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 Îł\gamma-nucleus and Îł\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

    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

    Soft QCD and Diffractive Physics at Lhc

    Get PDF
    After a short introduction on the importance of the soft and of the diffractive studies in the understanding of minimum bias events, the main results obtained at LHC are discussed. This overview includes identified particle and inclusive measurements, minimum bias and underlying events, all of them shedding light on the soft process production mechanisms. The results of the inelastic cross-section measurements obtained by the LHC experiments and their compatibility are discussed together with the models used to extrapolate the data at low diffractive masses. A review of the most recent diffraction results is presented, showing the different approaches used by the LHC experiments, relying on different experimental techniques. The combination of the results obtained by ALICE, ATLAS, CMS, LHCb and TOTEM provides a wide sample of informations, covering an unprecedented pseudorapidity range. A detailed comparison between the obtained results is shown, followed by a critical discussion on the still existing discrepancies between the experimental data and the Monte Carlo used at LHC to simulate soft and diffractive physics
