Dark Matter Indirect Searches

Talk

New interesting results on high-energy spectra of electron, positron and antiproton cosmic rays have been obtained in the recent years by balloon borne and satellite experiments. The data have been theoretically studied in an extensive way in terms of dark matter annihilation signals, pulsar contributions, new mechanisms of acceleration and propagation of cosmic rays in the Galaxy. A...

Dark Matter Indirect Searches

Talk

The observation by PAMELA of a rising positron fraction up to 100 GeV, further complemented with the ATIC / Fermi / HESS data on the electron+positron spectrum up to a few TeV, has led to significant adjustments in our understanding of the local high energy electron-positron budget. Many interpretation attempts have invoked dark matter annihilation or decay to fill the gap between the...

Dark Matter Indirect Searches

Talk

Some of the antimatter (antiprotons or positrons) present in cosmic rays could be due to the annihilation of dark matter particles. Indirect searches based on these signals require to be able to model the propagation process, from the annihilation location to the Solar System. The physical processes are well known : diffusion, convection, energy losses and reacceleration. The physical...
