单词 Z boson
释义

Z boson

原声例句
经济学人 Science and technology

Instead, it predicts the ratio of its mass to that of a z boson, the other weak-nuclear-force carrier.

相反, 它预测了它的质量与 z 玻色子(另一种弱核力载体) 的质量之比。

经济学人 Science and technology

The z' boson of the flavour force would interact with the z boson of the weak nuclear force and thus alter the predicted ratio.

味力的 z' 玻色子将与弱核力的 z 玻色子相互作用,从而改变预测的比率。

经济学人 Science and technology

Put the z boson's mass, which has been measured experimentally, into the altered ratio, says Dr Allanach, and out comes a w boson mass prediction that is much closer to the Fermilab measurement.

将已通过实验测量的 z 玻色子质量放入改变的比率中, Allanach 博士说,然后得出更接近费米实验室测量结果的 w 玻色子质量预测。

Bosón Z
Bosón W.

在物理学中,W及Z玻色子boson)是负责传递弱核力的基本粒子。它们是1983年在欧洲核子研究组织发现的,被认为是粒子物理标准模型的一大胜利。

W玻色子是因弱核力的“弱”(Weak)字而命名的。而Z玻色子则半幽默地因是“最后一个要发现的粒子”而名。另一个说法是因Z玻色子有零(Zero)电荷而得名。

Bosón Z

The W and Z bosons are together known as the weak or more generally as the intermediate vector bosons. These elementary particles mediate the weak interaction; the respective symbols are W+, W, and Z. The W bosons have a positive and negative electric charge of 1 elementary charge respectively and are each other's antiparticles. The Z boson is electrically neutral and is its own antiparticle. The three particles have a spin of 1. The W bosons have a magnetic moment, but the Z has none. All three of these particles are very short-lived, with a half-life of about 3×10 s. The experimental discovery was a triumph for what is now known as the Standard Model of particle physics.
