neutralino

基本解释

Terrestrial radioactivity typically outpowers the putative neutralino signal by a factor of 106.
地球上放射性的典型强度，是假设的中性伴子讯号的106倍以上；
The hypothesized mass, stability and neutrality of the neutralino satisfy all the requirements of cold dark matter.
中性伴子的质量、稳定性和电中性满足了冷暗物质所要求的各种性质。
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。
As the name implies, the neutralino has zero charge, so it is unaffected by electromagnetic forces (such as those involving light).
从中性伴子的命名可知，它的电荷为零，因而它不会受到电磁力（比如光）的影响。
If so, it has to be stable: if a superparticle is unstable, it must decay into two lighter superparticles, and the neutralino is already the lightest.
这样一来，它无疑是稳定的：假如一个超对称粒子不稳定，它必然会衰变成两个更轻的超对称粒子，而中性伴子已经是最轻的了。
