neutralino |
释义 |
1 ?超中性子 ...被称为“惰性”中微子。惰性中微子与普通物质只发生引力相互作用,科学家相信它也是暗物质的候选者之一。 超中性子(Neutralino):是一种由超对称理论预言的假想粒子。超对称理论假设标准模型中所有的基本粒子都有与之对应的超对称粒子,这些粒子足以构成暗物... 2 ?中性伴随子 目前物理学家认为有可能是黑暗物质的粒子很多,其中之一是称作中性伴随子(neutralino)的中性超对称粒子。但超对称理论是否正确,以及中性伴随子是否存在,都还是未知。 3 ?渺中子 现在希望放在了其他两个候选者身上:(1)渺中子(neutralino),它的质量是质子质量的100倍,是弦理论所预言的最轻的粒子;(2)轴子(axion),它的质量比电子小一万亿倍。

For example, background particles tend to produce more ionization than a nucleus recoiling from a neutralino collision. 例如,背景粒子和一个与中性伴子碰撞而反冲的原子核相比,前者将造成更多的游离。 - 2
It will therefore be possible to work out which direction the neutralino that caused it to recoil came from and thus engage in a form of dark-matter astronomy. 由此就可以计算出发生碰撞的中轻微子的来向,甚至产生一门暗物质天文学。 - 3
In fact, based on the expected neutralino mass and its low tendency to collide, the total mass in neutralinos almost exactly matches the inferred mass of dark matter in the universe. 事实上,从中性伴子预估的质量及它不易碰撞的倾向可得出:中性伴子的总质量与我们推算宇宙中暗物质的质量几乎完全相同。
