利用轻子宇宙射线探测暗物质

Dark Matter detection via lepton cosmic rays

Roberto A. Lineros

摘要:

最近的PAMELA和FERMI实验对轻子宇宙射线的观测,将我们对星际介质和宇宙射线源的理解推向了前所未有的水平。暗物质在轻子宇宙射线上的印记是对PAMELA的正电子过剩和FERMI的总电子通量的最令人兴奋的解释。或者,超新星是具有解释这些观测结果的相同潜力的天体物理学对象。在这项工作中,我们提出了轻子宇宙射线的天体物理来源和暗物质信号的正电子过剩和电子总通量的可能痕迹的最新研究。

英文摘要:

Recent observations of lepton cosmic rays, coming from the PAMELA and FERMI experiments, have pushed our understanding of the interstellar medium and cosmic rays sources to unprecedented levels. The imprint of dark matter on lepton cosmic rays is the most exciting explanation of both PAMELA's positron excess and FERMI's total flux of electrons. Alternatively, supernovae are astrophysical objects with the same potential to explain these observations. In this work, we present an updated study of the astrophysical sources of lepton cosmic rays and the possible trace of a dark matter signal on the positron excess and total flux of electrons.
