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(qiáng)度，是假設(shè)的中性伴子訊號(hào)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(gè)與中性伴子碰撞而反沖的原子核相比，前者將造成更多的遊離。
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，它的電荷爲(wèi)零，因而它不會(huì)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(gè)超對(duì)稱粒子不穩(wěn)定，它必然會(huì)衰變成兩個(gè)更輕的超對(duì)稱粒子，而中性伴子已經(jīng)是最輕的了。
