Testing astrophysical models for the PAMELA positron excess with cosmic ray nuclei.

Testing astrophysical models for the PAMELA positron excess with cosmic ray nuclei.

The excess in the positron fraction measured by PAMELA has been interpreted as due to annihilation or decay of dark matter in the Galaxy. More prosaically it has been ascribed to direct production of positrons by nearby pulsars or due to pion production during diffusive shock acceleration of hadroni...
