Charged current

原声例句
CNN 10 学生英语 2023年4月合集

This is the first time in U.S. history that a current or former president has been criminally charged.

这是美国史上首次有现任或前任总统受到刑事指控。

PBS太空科学

In the sun's super-hot center, atoms are stripped of their electrons and boil to the surface along charged convection currents as wide as Texas.

在太阳的超热中心，原子被剥夺了电子，并沿着与得克萨斯州一样宽的带电对流沸腾到表面。

带电流

带电流（英文：Charged current）相互作用是亚原子粒子间弱相互作用的一种形式，由W+及W-玻色子传递。

这一相互作用的名字中的“带电（charged）”常常被错误地认为得名于带电的W玻色子。实际上，这一名字应源于参与相互作用的粒子。例如，带电流相互作用对于ν
ee− → ν
ee−弹性散射的射程所做出的贡献：

\mathfrak{M}^{\mathrm{CC}} \propto J_{\mu}^{\mathrm{(CC)}}(\mathrm{e^{-}}\to\nu_{\mathrm{e}}) \; J^{\mathrm{(CC)}\mu}(\nu_{\mathrm{e}}\to\mathrm{e^{-}})

其中，描述了由一个费米子流向另一个费米子的带电流由下式给出：

J^{\mathrm{(CC)\mu}}(f\to f') = \bar{u}_{f'}\gamma^{\mu}\frac{1}{2}\left(1-\gamma^{5}\right)u_{f}.

Charged current 带电流

The Charged current interaction is one of the ways in which subatomic particles can interact by means of the weak force. It is mediated by the W+ and W− bosons.

The interaction is often incorrectly believed to be called 'charged' because the W bosons have electric charge. However, the charged current that gives the interaction its name is that of the interacting particles. For example, the charged-current contribution to the ν
ee− → ν
ee− elastic scattering amplitude
