带电的宇宙射线在暗物质上告诉我们什么

What charged cosmic rays tell us on dark matter

Pierre Salati

摘要:

暗物质粒子可能是星系晕的主要成分。它们的相互湮灭或衰变会产生高能宇宙射线形式的间接信号。本报告的重点是反物质种类,一种非常罕见的成分,任何超出背景的成分都很容易被检测到。在回顾了银河系的传播之后,我将讨论正电子、反质子和反核。对于这些物种中的每一个,都有异常的报道。例如,反质子过剩是当前的一个热门话题。唉,它并不能抵制对理论和数据错误的正确处理。

英文摘要:

Dark matter particles could be the major component of the haloes of galaxies. Their mutual annihilations or decays would produce an indirect signature under the form of high-energy cosmic-rays. The focus of this presentation is on antimatter species, a component so rare that any excess over the background should be easily detected. After a recap on Galactic propagation, I will discuss positrons, antiprotons and anti-nuclei. For each of these species, anomalies have been reported. The antiproton excess, for instance, is currently a hot topic. Alas, it does not resist a correct treatment of theoretical and data errors.
