So it emits phased muon particles.

它阶段性放射出定相μ介子。

A muon is one of the so-called elementary particles, one with no smaller parts.

These may be an electron and its antimatter equivalent, a positron, or two heavier leptons, a muon and an antimuon.

它们可能一个电子和它的反物质等价物，一个正电子，或者个更重的轻子，一个介子和一个反介子。

Now, does anyone know what happens to quarks when we combine them to make mesons and baryons?

有人知道当我们把夸克组合成介子和重子时什么吗？

Searching for those differences is one of the tasks for the people at the Compact Muon Solenoid, or CMS.

寻找这些差异紧凑介子螺线管(CMS)工作人员的任务之一。

The CDF team think they have found a bit more of it, in particles known as D0-mesons.

CDF团队认为，他们在一种名为D0-介子的粒子中现的违逆比允许量多出了一点。

The muons last for only two microseconds.

介子只持续微秒。

Scientists used muons, a by-product of the cosmic rays constantly raining down on our planet, to image the interior of the pyramid.

科学家用μ介子来描绘金字塔内部的情况，μ介子一种持续落到地球上的宇宙射线的副产品。

" what is the iso-spin singlet partner of the pi-zero meson? "

π零介子的同重旋单重配合物什么?

The details are arcane. But they concern particles called beauty quarks which, themselves, form part of other particles called B-mesons.

细节晦涩难懂。但他们关注的一种叫做“美夸克”的粒子，这种粒子本身另一种叫做“B-介子”的粒子的一部分。

The data it gathers help scientists in their search for things like extra dimensions, dark matter and new particles like the Higgs.

它收集的数据帮助科学家寻找额外维度、暗物质和希格斯介子等新粒子。

Something to separate the men from the boys, the wheat from the chaff, the mesons from the pi-mesons, the quarks from the quacks.

来看看你们男人，还男孩，粮食，还糟糠，介子还 π 介子，真夸克（基本粒子之一）还庸医。

The same was found for electrons, which have heavier siblings called the muon and the tau.

电子也有同样的现，它们有更重的兄弟姐妹， 称为 μ 介子和 tau。

Okay. Get this. " Professor Jones told the symposium he had a new method " for calculating the mass of a muon.

好了，听听这个。琼斯教授在研讨上说，他找到了计算μ介子质量的新方法。

Others, though, have a different explanation for the b meson decay anomaly—a proposed new particle called a leptoquark.

不过，其他人对 b 介子衰变异常有不同的解释——一种被提议称为轻夸克的新粒子。

The b meson anomaly challenges this idea.

b 介子异常挑战了这个想法。

Photons, carriers of the electromagnetic force, interact with electrons, muons and taus in identical ways.

The lightest generation contains the electron; a second, heavier, generation, the muon; the third and heaviest, the tau.

最轻的一代包含电子；第二代，更重的一代，介子；第三个也最重的，tau。
