摘要

PAMELA实验从2006年开始收集数据;结果表明，在10gev以上的CR谱中，相对于电子存在较大的正电子通量。这种过剩也可能起源于脉冲星和微类星体等天体，或者源于暗物质的湮灭。本文对PAMELA收集的电子和正电子事件进行了分析，寻找各向异性。分析是在不同的角度尺度上进行的，结果将在会议上公布。

A method to detect positron anisotropies with Pamela data

The PAMELA experiment is collecting data since 2006; its results indicate the presence of a large flux of positron with respect to electrons in the CR spectrum above 10 GeV. This excess might also be originated in objects such as pulsars and microquasars or through dark matter annihilation. Here the electrons and positrons events collected by PAMELA have been analized searching for anisotropies. The analysis is performed at different angular scales and results will be presented at the conference.
