W Boson
原声例句
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。

W and Z bosons   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. |
