对AMS02结果的评论支持cosmic ray正电子的次级起源

Comment on AMS02 results support the secondary origin of cosmic ray positrons

Shlomo Dado, Arnon Dar

摘要:

我们提出了一个简单的计算的次级正电子的流量在ISM中产生的是只基于先验。我们计算的ISM通量与用GALPROP程序计算的结果吻合得很好。它证实了由初级宇宙射线在ISM中产生的次级正电子不能解释观测到的CR正电子的亚TeV通量。此外,我们表明,一旦源和ISM中的正电子的能量损失被包括在内,二次生产内的CR源加上ISM解释测量的近地宇宙线正电子通量。

英文摘要:

We present a simple calculation of the flux of secondary positrons produced in the ISM that is based only on priors. Our calculated ISM flux agrees very well with that calculated with the elaborate GALPROP code. It confirms that secondary production of positrons in the ISM by the primary cosmic rays cannot explain the observed sub-TeV flux of CR positrons. Moreover, we show that once energy loss of positrons in source and in the ISM are included, secondary production inside the CR sources plus the ISM does explain the measured near-Earth flux of cosmic ray positrons.
