一旦承认有可能存在性质超越标准弱相互作用重粒子的粒子,人们自然而然会联想还有没有其它可能。
Once one admits the possibility of hidden particles with properties that go beyond the standard WIMP scenario, it is natural to consider the full range of possibilities.
从很早以前开始,物理学界就一直在寻找关于暗物质的一切,一种最流行的探索途径是寻找WIMPs,即弱作用重粒子。
Physicists have long wondered about dark matter. One of the most popular explanations is that it consists of weakly interacting massive particles, also known as WIMPs.
一种被称为“超对称性”的粒子理论预言了“弱作用重粒子”(WIMPs)的存在——它也许就是暗物质粒子。
A particle theory called "supersymmetry" predicts the existence of weakly interacting massive particles (WIMPs), which could be the particles of dark matter.
有证据表明宇宙中锂元素的含量比预计要少,所以假设的超级弱相互作用重粒子可以作为一种方法解释这种差异。
There is some evidence that the universe has less lithium than expected, and the super-WIMP hypothesis is one way to explain the discrepancy.
而且,在弱相互作用重粒子衰变成超级弱相互作用重粒子过程中,应该产生光子和电子等副产品,并且这些粒子也会与质量较轻的原子核发生碰撞,将它们撞碎。
In addition, the decay from WIMP to super-WIMP should have produced photons or electrons as a by-product, and these particles can smash into light nuclei and break them apart.
粒子间相互作用得越多,则越重,因此从不与其他粒子相互作用的粒子完全没有质量。
The more they interact, the heavier they become, whereas particles that never interact are left with no mass at all.
结果表明,湿法超细改性重质碳酸钙具有无机刚性粒子的增强增韧作用,其应用效果明显优于活性轻质碳酸钙。
It was showed that the former has the better function of the inorganic rigid granule to enhance the strength and toughness of the compounds, so it is obviously superior to the latter.
