But they could cause a proton to decay — a very big deal, if it turns out to be correct, since proton decay isn't allowed under the current Standard Model of particle physics.

但是它们可能导致质子衰变，如果这个假设被证明是正确的，这将是一个大问题。因为在现有粒子物理的标准模型中质子是不能衰变的。

The first type discovered -- alpha decay -- is when a radioactive particle emits a Helium nucleus !

我们发现的第一种衰变方式——阿尔法衰变——是放射性粒子产生氦分子！

So these monopoles could well turn up in our particle acceleratorsor in the decay products of cosmic ray collisions in the upper atmosphere.

所以这些单极在粒子加速器里或者在高空大气宇宙射线的碰撞过程中可能会被找到。

At the time of Higgs' discovery, observers were especially interested in the possibility that this mysterious particle didn't decay in exactly the way science had predicted.

It is unclear how solar particles affect rates of radioactive decay, but Prof Jenkins asserts that "either neutrinos are affecting the decay rate or perhaps an unknown particle is".

Radioactive decay happens when a radioactive substance emits a particle.
