Scientists propose new source for rare subatomic particles

A paper based on joint research by Prof. Yuan Changzheng from Institute of High Energy Physics of the Chinese Academy of Sciences, and Prof. Marek Karliner from Tel Aviv University of Israel, was published in Physical Review Letters. It points out a new abundant source of antineutrons and hyperons. These rare subatomic particles are essential for studying forces governing the behavior of matter at the smallest distances, from atomic nuclei to neutron stars

Physicists investigate the subatomic world by bombarding their subjects with a hail of tiny subatomic 'bullets'. Based on how these 'bullets' bounce off their target, one can infer a wealth of detailed information about the target's structure. This method was pioneered by Ernest Rutherford, who used it to discover the atomic nucleus more than 100 years ago. Different kinds of subatomic 'bullets' probe different aspects of the target, just like X-rays, MRI and PET scanners reveal various essential features of a body part in medical imaging. Certain important aspects of the force holding atomic nuclei together can only be investigated by shooting particles called antineutrons and hyperons, which are currently very difficult to produce and control.
