Abstract

The measurements of electrons from cosmic rays have begun a new era a few years ago with high precision experiments like PAMELA and Fermi-LAT. The positron fraction seems to indicate an unknown component above the standard background described in the last 40 years, mostly by HEAT. In the last few years, the PAMELA satellite has confirmed the positron fraction excess above 10 GeV, and studying Fermi-LAT data, the electron flux seems to be steeper than expected. While these new measurements have not closed the debate, results from AMS-02 are expected to reach the accuracy needed to determine a full description of this excess and possibly give some evidence on the possible source. We will present in this note, the AMS-02 capacity in the case of positrons produced by pulsars.
