The basic presupposition of quark theory is that quark itself is a truly integrated basic particle, a point-like object with no internal components.
最新的观测涉及到被称为介子的夸克的组合,特别是D0(“d-0”)介子和反D0介子。
The latest observations involved combinations of quarks called mesons, specifically the D0("d-zero") meson and the anti-D0 meson.
更确切地说,这些国家必须由两个夸克,一个向下夸克,一个魅力夸克和一个反魅力夸克组成。
More precisely, the states must be formed of two up quarks, one down quark, and one charm quark and one anti-charm quark.".
研究人员转向量子色动力学(QCD),这是标准模型的基石,描述了夸克和胶子如何相互作用。
The researchers turned to quantum chromodynamics(QCD), a cornerstone of the standard model that describes how quarks and gluons interact with each other.
这些稳定粒子会从探测器中逃逸,留下一个或多个高能夸克喷注的迹象,以及大量遗失动量。
The stable particles would escape the detector, leaving as a signal one or more high-energy quark jets and a large amount of"missing" momentum.
神秘的五夸克亚原子粒子--五夸克,几年前才被发现--实际上是由两组夸克组成.
The mysterious five-quark subatomic particle- the pentaquark, only discovered a few years ago- really is composed of two sets of quarks.
如果正确的话,它表明地球上的粒子加速器可能产生稳定的夸克物质。
If correct, it suggests that particle accelerators on Earth might be able to produce stable bits of the quark matter.
我们问他们,你没有学到任何东西,但你能告诉我们质子有多少个夸克吗?
But then we ask them, okay you did not learn anything, but can you tell us how many quarks are there in a proton?
这个发现很关键,因为ψ最终是由一个叫做魅力夸克和它的反物质伙伴的粒子组成的。
The discovery was key because the ψ turned out to be made of a particle called the charm quark and its antimatter partner.
现在,科学家已经能够处理更多的数据,以了解夸克如何排列在这些奇怪的五夸克粒子中。
Now, scientists have been able to crunch even more data to understand how the quarks are arranged in these odd pentaquark particles.
更确切地说,这些国家必须由两个夸克,一个向下夸克,一个魅力夸克和一个反魅力夸克组成。
More precisely the states must be formed of two up quarks, one down quark, one charm quark and one anti-charm quark.”.
有时他说那是超导体的涡流线,其他时候他称它们为连接夸克的弦。
Sometimes he said they were vortex lines, found in superconductors; other times he called them strings, connecting quarks.
在标准模型中,理解这些粒子的理论,应该有三种产生夸克的方法。
Under the Standard Model, the theory by which these particles are understood, there should be three ways of producing quarks.
盖尔曼和茨威格假定它们不是基本粒子,而是由夸克和反夸克组成的。
Gell-Mann and Zweig posited that they were not elementary particles, but were instead composed of combinations of quarks and antiquarks.
然而,强核力还有一个叫做渐近自由的性质,它使得夸克和胶子成为定义得很好的概念。
However, there is another property of the strong nuclear force, called asymptotic freedom, that makes the concept of quarks and gluons well defined.
那是由于夸克严密地结合在一起,咱们无法轻易地把它们分隔。
That's because the quarks bind together so tightly that we can't separate them easily.
夸克以色荷为载体通过强力相互作用色荷分三种红绿蓝.
The strong force acts between quarks which carry a different kind of charge, called color charge, and come in three different varieties: red, green and blue.
这项工作导致夸克这一基本粒子的发现,并最终建立了粒子物理学的标准模型。
This work led to the discovery of elementary particles known as quarks, and ultimately to the establishment of the standard model of particle physics.
夸克可以改变它们的颜色电荷,胶子也可以改变,因为为什么不呢。
The quarks can change their color charge, and the gluons can too, because why not.
相反地,夸克在量子色动力学中扮演着定义的角色,量子色动力学是负责完全描述强相互作用的理论;.
Conversely, the quarks serve in the definition of Quantum chromodynamics, the fundamental theory fully describing the strong interactions;
