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

它收的助家寻找额外维度、暗物质和希格斯介子等新粒子。

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。琼斯教授在研讨会上说，他找到了计算μ介子质量的新方法。

When a D0-meson decays, it produces daughter particles called pions and kaons.

D0-介子衰变时会产生叫做π介子和K介子的子粒子。

And so, we think that all the subatomic particles of the universe, the quarks, the neutrinos, the mesons, the protons, the neutrons, there's a galaxy of these particles, they're nothing but musical notes on a tiny rubber band.

所以我们认为所有的亚原子宇宙的粒子，夸克、中微子、介子、 质子和中子有一个由这些粒子组成的星系，它们只不过是一个小橡皮筋上的音符。

But an analysis of results from the LHCB experiment (pictured), a purpose-built detector fitted to CERN's Large Hadron Collider (LHC), suggests electron-positron pairs are more abundant than muon pairs.

但是对LHCB(欧洲核子研中心的大型强子对撞机(LHC)专用探测器)实验结果的分析表明，电子-正电子的量对比介子对更多。

Physicists unveiled the first results of the Muon g — 2 experiment in April this year, and are expected to publish more precise results in 2023.

物理家在今年4月公布了μ介子g-2实验的第一批结果，预计将在2023年公布更精确的结果。

However, it's still debated that Jie Zitui was the reason that the Cold Food Festival was started in the first place.

然而， 关于介子推是否是寒食节最初开始的原因仍存在争议。

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

来看看你们是男人，还是男孩，是粮食，还是糟糠，是介子还是 π 介子，真夸克（基本粒子之一）还是庸医。

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

家用μ介子来描绘金字塔内部的情况，μ介子是一种持续落到地球上的宇宙射线的副产品。

These might be anything from a field biologist's notes of lemming populations on Spitzbergen to a physicist's creation of muon tracks in a cloud chamber, or from a set of equations in the mathematical imagination to a vast computer model of the world's climate.

在这本书中你将会看到野外生物家对于斯匹茨卑根群岛上的旅鼠种群的阐述，物理家在云室里创建的μ介子轨迹，利用概念思考出的一组方程式，以及巨型计算机模型中的全球气候。

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

寻找这些差异是紧凑介子螺线管(CMS)工作人员的任务之一。

When I was an undergraduate, we made fun of the old professors who didn't understand the theory of mesons.

我读本的时候也经常和同取笑那些不懂介子理论的老教授。

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

介子是所谓的基本粒子之一，且不能再分。

So it emits phased muon particles.

它会阶段性放射出定相μ介子。

The experiment studies how short-lived particles known as muons behave in magnetic fields, and creates a sensitive test of the standard model of particle physics.

该实验研了被称为μ介子的短寿命粒子在磁场中的行为，并对粒子物理的标准模型进行了灵敏测试。

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。但他们关注的是一种叫做“美夸克”的粒子，这种粒子本身是另一种叫做“B-介子”的粒子的一部分。

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

它们可能是一个电子和它的反物质等价物，一个正电子，或者两个更重的轻子，一个介子和一个反介子。

So he ordered to build a temple for Jie Zitui and asked people to eat warm food instead.

于是他下令为介子推建立寺庙，要求人们吃热食。

So some people believed that eventually this firewood changing practice was combined with the commemoration of Jie Zitui and developed into the Cold Food Festival.

所以，也有人认为，这种换柴的习俗最终与纪念介子推结合起来，发展成为寒食节。

The neutrinos themselves are created by smashing bunches of protons into a target made of graphite.

中微子产生于一些质子束轰击一个石墨目标后产生脉冲介子，介子随后衰变而成。
