Asquith, like many physicists, spends a lot of time thinking about particles like the elusive Higgs boson - the subatomic particle that scientists say endows everything in the universe with mass.

阿斯奎斯像其他许多物理学家一样花了很多时间来思考像希格斯玻色子那样难以捉摸的微粒子——被科学家推测其普遍存在于大自然万物中的一种微粒子。

that the negative particle travelled - it was deflected much, much further by those plates, what he could also assume and make the conclusion of is that the mass of that negative particle is actually larger or smaller?

因为他发现负电粒子,运动了很远,它被两块电板偏转了,非常非常远,所以他给出的结论是,负电粒子的质量,是比较大还是比较小？

And since we are not expecting the mass of the particle to change, what we really are saying is the uncertainty in its velocity times the uncertainty in its position is greater than the ratio of the Planck constant divided by 2 pi.

因为我们不期望,粒子质量发生变化，我们说的是,它速度的不确定度,乘以它位置的不确定度,比普朗克常量,除以2除以圆周率要大。

An analysis of these smash-ups indicates the mass of the particle being sought.

WSJ: New Data Boosts Case for Higgs Boson Find

The frequency at which it happens is related to a small but significant difference between the mass of the particle and its antiparticle.

ECONOMIST: Cosmology and particle physics

Because nobody knows what the mass of a Higgs boson might be, the particle must be hunted indirectly, typically in giant machines that propel particles to near-light speed, then smash them together and generate an array of other subatomic particles.
