  1. 115. Understanding Cosmic Rays and searching for Dark Matter with PAMELA
    Dr Roberta Sparvoli (University of Rome ”Tor Vergata”, and INFN Section of Rome ”Tor Vergata”, Rome, Italy)
    09/12/2010, 17:00
    After four years of data taking in space, the experiment PAMELA is showing very interesting features in cosmic rays that might change our basic vision of their mechanisms of production, acceleration and propagation in the galaxy. In addition, PAMELA measurements of cosmic antimatter fluxes are setting strong constraints to the nature of Dark Matter. In this talk PAMELA main results will be...

  2. 83. Cosmic Sum Rules

    Cosmology and astroparticles, dark matter searches
    We introduce new sum rules allowing to determine universal properties of the unknown component of the cosmic rays and show how they can be used to predict the positron fraction at energies not yet explored by current experiments and to constrain specific models.

  3. 124. Search for Dark Matter in Cosmic Rays with the AMS-02 space spectrometer.
    Prof. Federico Palmonari (INFN and University, Bologna)

    Cosmology and astroparticles, dark matter searches
    The growing observational evidence for Dark Matter from astrophysical observations gives a solid base to the Cosmological Standar Model. On the other side, the Standard Model of particles and interactions has no answer on DM nature. Experimental evidence of DM from underground experiments is under scrutiny while recent results from space experiments have no clear interpretation. The...

  4. 53. ANTIMATTER AND DARK MATTER : GALAXY STRUCTURE , FLARES AND COSMIC RAYS
    Dr Maurice LALOUM (retired CNRS/IN2P3/LPNHE Paris)
    09/12/2010, 18:15
    Cosmology and astroparticles, dark matter searches
    Many essential paradoxes in the mechanical balance of the Galaxy are highlighted. We propose a unique and synthetic interpretation, including a cosmological theory of the origin of the observed cosmic rays, especially at the highest energies. It involves MATTER-ANTIMATTER ANNIHILATION in the median plane of the Milky Way, as a source of "DARK MATTER". We discuss the structure and balance of...
