New Insights into How Strange Matter Interacts with Ordinary Matter
Scientists reported the first observations of how nuclei containing strange quarks flow from particle collisions that smash atomic nuclei together at high energies. They specifically tracked the flow patterns of so-called hypernuclei. These hypernuclei contain particles called hyperons (made of at least one strange quark) in addition to ordinary protons and neutrons (known as nucleons).
