neutralino meaning in English

微子

The neutralino is a particularly collision - shy particle , so it froze out early on
中性伴子特别害羞，不易与其他粒子相撞，所以它很早就冷却出来了。
Although the neutralino is heavy by normal standards , it is generally thought to be the lightest supersymmetric particle
虽然按一般标准，中性伴子的质量很大，但它是超对称粒子中最轻的。
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。
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。
