A possible explanation for the electron/positron excess of ATIC/PAMELA

Rui-Zhi Yang, Jin Chang, Jian Wu

Abstract

Results from PAMELA and ATIC indicate that the Kaluza-Klein type dark matter particles could be the annihilation source of the observed excess of electrons and positrons. Assuming the existence of a nearby black hole with 10 000-100000 solar masses and a point source boost algorithm, we apply the standard propagation model and find that the results fit the data well.
