neutralino

基本解釋

Terrestrial radioactivity typically outpowers the putative neutralino signal by a factor of 106.
地球上放射性的典型強度，是假設的中性伴子訊號的106倍以上；
The hypothesized mass, stability and neutrality of the neutralino satisfy all the requirements of cold dark matter.
中性伴子的質(zhì)量、穩(wěn)定性和電中性滿足了冷暗物質(zhì)所要求的各種性質(zhì)。
For example, background particles tend to produce more ionization than a nucleus recoiling from a neutralino collision.
例如，背景粒子和一個與中性伴子碰撞而反沖的原子核相比，前者將造成更多的游離。
As the name implies, the neutralino has zero charge, so it is unaffected by electromagnetic forces (such as those involving light).
從中性伴子的命名可知，它的電荷為零，因而它不會受到電磁力（比如光）的影響。
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.
這樣一來，它無疑是穩(wěn)定的：假如一個超對稱粒子不穩(wěn)定，它必然會衰變成兩個更輕的超對稱粒子，而中性伴子已經(jīng)是最輕的了。
