Descrizione del progetto

The final goal of the project is to outline a consistent model for the production and propagation of cosmic matter and antimatter in the Galaxy, testing a possible tiny component coming from the Dark Matter (DM) particles annihilating in the Galaxy. With the resources coming from the project, we plan to:

  • WP1: refine a model for the production of cosmic electrons (e-) and positrons (e+) from GeV to TeV energies, in terms of a secondary e+ and e- due to the inelastic interactions of proton and helium with the interstellar gas, a source (equal e+ e-) in the pulsar wind nebulae, and a contribution due to e- acceleration in the supernova emnants. We will test our model on the most recent data taken from space and ground based telescopes.

  • WP2: test the results of WP1 on the most recent data on the e-e+ dipole anisotropy. We will employ all the available radio data from local sources (supernova remnants) simultaneously with the e- and e+ data, aiming at excluding for the first time a number of models from the anisotropy data.

  • WP3: adding to the astrophysical models surviving the analysis at WP1 and WP2 also the contribution from DM annihilating into e+ in the Galaxy. We will confront our model with the most recent (AMS02) data and outline or constrain this exotic source in the CR data.

  • WP4: perform Monte Carlo Simulation for studying the feasibility of the pbar production cross-section measurements with the COMPASS detector at CERN using protons at different momenta on targets of liquid hydrogen and liquid helium.

  • WP5: analyze already available proton on liquid hydrogen COMPASS data at 190 GeV/c, to tune the simulation parameters and possibly improve the final feasibility study results.

  • WP6: using the results from WP4 and WP5, we will estimate how the cosmic antiproton source term could get improved by the COMPASS data.

Tutti i punti previsti dal progetto sono stati realizzati. In aggiunta,é stato scoperto un alone diffuso di raggi gamma attorno alla pulsar Geminga. Questa scoperta ha comportato una pubblicazione aggiuntiva, e comunicati stampa presso la NASA/Goddard e l'INFN.
