【摘要】：本文簡介了暗物質(zhì)間接探測的最新進展.主要介紹近年來PAMELA(Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics)衛(wèi)星所探測到的宇宙線正電子超出的問題,及相關(guān)的理論解釋.本文還介紹了PAMELA對于宇宙線反質(zhì)子的測量結(jié)果,ATIC和Fermi衛(wèi)星對于正負電子總能譜的測量結(jié)果等.另一個重要的結(jié)果來自于Fermi和地面實驗對于伽馬射線的測量結(jié)果,這些結(jié)果對暗物質(zhì)性質(zhì)給出較強的限制.
[Abstract]:In this paper, the latest progress in indirect detection of dark matter is introduced. This paper mainly introduces the problem of cosmic ray positron excess detected by PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics satellite in recent years and the related theoretical explanation. The PAMELA measurements of cosmic ray antiprotons and the measurements of the total energy spectra of positron and negative electrons by Fermi satellite are also presented in this paper. Another important result comes from the results of Fermi and ground experiments on gamma ray measurements, which limit the properties of dark matter strongly.
