Experiments at the Large Hadron Collider in Italy are aiding the study of dark matter.
上周,研究人员在LHC室内砸碎了质子针对氦核。通常,LHC托有质子固有质子碰撞。
The latest collisions旨在复制宇宙射线颗粒与星际“灰尘”颗粒之间的相互作用。宇宙射线颗粒是来自太阳系外部的高能量颗粒。星际灰尘颗粒是最常见的星际介质,主要由氢和氦组成。
科学家希望这些碰撞将有助于寻找黑物质 - 占宇宙25%的无形物质。研究人员尚未直接证实暗物质的存在,但是科学家假设暗物质颗粒的碰撞会产生普通的颗粒和抗颗粒,包括抗抑制剂。
Proton-helium collisions also produce antiprotons. The latest experiments will help scientists measure the number of antiprotons yielded by proton-helium interactions. The information could potentially help physicists identify antiprotons produced by dark matter collisions in interstellar space.
For example, an expected number of antiprotons could reveal the presence of dark matter. But currently, scientists need a more precise understanding of proton-helium collisions.
科学家目前正在使用一对宇宙射线研究卫星Pamela和AMS-02分析质子螺旋碰撞。科学家希望LHC实验将帮助天文学家更加清晰地解释Pamela和AMS-02数据。
