1·Those more-refined analyses have not seen the hypothetical new particle, so for some reason it must not decay into bottom quarks.
那些更精细的分析并没有发现这种假设的粒子，所以，也许它因为某些原因并不会衰变成底夸克。
2·But in this new research, the idea was to alter mass of all the quarks, not just one of them.
但在这项新的研究中，思路是改变所有夸克的质量，而不仅仅是一个。
3·A quark cannot exist on its own, but must be bound to other quarks or an antiquark.
一个夸克不能单独存在，必须与其它夸克或反夸克结合在一起。
4·What if the earliest particles to form — such as quarks — had slightly different masses than we measure today?
如果最早形成的粒子——比如夸克——的质量与我们今天的测量值稍有不同呢？
5·This Lamb shift is a result of the interactions between the electron and the constituent quarks of the proton as described by QED.
兰姆位移是电子与质子组分夸克相互作用的结果，这一现象被描述为量子电动力（QED）。
