But the lead ion collisions will be different; because lead ions are composed of complete atomic nuclei - not just a single subatomic particle - their masses are far larger.

但是铅离子的对撞将会是不同的；因为铅离子完全由原子核组成——而不仅仅只是一个单一的亚原子粒子(subatomic particle)——它们的质量要大得多。

Ozone is tri-atomic oxygen (O3) - it is a highly charged, volatile particle.

臭氧是三原子氧（O3）的 - 这是一个高度紧张，易挥发粒子。

Some of their work involved X-rays produced by particle accelerators, devices that bring atomic particles into high energies.

Although this might seem a little esoteric, discovery of this baryon provides further proof of the validity of the Standard Model of Particle Physics, and helps contribute to our understanding of atomic interactions.

FORBES: Large Hadron Collider Discovers Beautiful New Particle

Dr Kobayashi and Dr Maskawa, who were at Japan's High Energy Accelerator Research Organisation and Kyoto University respectively, described a type of symmetry breaking that predicted two new families of quarks, a sort of subatomic particle whose simplest members are the ingredients of the protons and neutrons that form atomic nuclei.
