Abstract

Being generated, the relic neutrino background contained equal fractions of electron \({{\nu }_{e}}\), muon \({{\nu }_{\mu }}\), and taon \({{\nu }_{\tau }}\) neutrinos. We show that the gravitational field of our Galaxy and other nearby cosmic objects changes this composition near the Solar System. As a result, the relic background becomes enriched with taon and particularly muon neutrinos. The electron relic neutrinos are the rarest for a terrestrial observer.

从地球看遗物中微子的组成

摘要

产生后，残留的中微子背景包含等分的电子\（{{\ nu __ {e}} \}，muon \（{{\ nu _ {\ mu}} \）和taon \（{ \ nu} _ {\ tau}} \）中微子。我们表明，银河系和附近其他宇宙物体的引力场会改变太阳系附近的这种成分。结果，文物背景富含牛，尤其是μ子中微子。电子遗留的中微子对于地面观察者来说是最稀有的。
