gluon

n.[核]胶子(一种理论上假设的无质量的粒子)

It doesn't do combinatorics like the gluon, so it should be out in the open and detectable in principle. 它不会像胶子那样组合，因此理论上它也是可以探测到的。

It turns out that one type of gluon chain behaves in the four-dimensional spacetime as the graviton, the fundamental quantum particle of gravity. 我们发现了一类胶子链，在四维时空中的行为就和重力子一样，重力子是重力现象的基本量子。
