通过磁透镜的PAMELA

PAMELA through a Magnetic Lens

J. P. Roberts

摘要:

PAMELA卫星观测到,在10 - 100 GeV的范围内,正电子与电子的比率超过理论预测,并随着能量的增加而增加。我们建议,过量是不是由于在本地星际光谱的变化,但由于日光层调制。我们从已知的日光层磁场的形式来激发这一点,并预测当我们进入太阳活动最活跃的时期时,多余的磁场将消失。

英文摘要:

The PAMELA satellite has observed an excess in the positron to electron ratio above theoretical predictions in the range 10 - 100 GeV that increases with energy. We propose that the excess is not due to a change in the local interstellar spectrum, but is due to heliospheric modulation. We motivate this from the known form of the heliospheric magnetic field and predict that the excess will disappear when we enter a period of solar maximum activity.
