ALICE Discovers Antimatter Counterpart of Hyperhelium-4

The ALICE collaboration at the Large Hadron Collider has found the first evidence of antihyperhelium-4, the heaviest antimatter hypernucleus observed at the LHC, with a significance of 3.5 standard deviations. This discovery, based on 2018 lead-lead collision data, supports the statistical hadronisation model's predictions and contributes to understanding the matter-antimatter asymmetry in the universe. The findings also include evidence of antihyperhydrogen-4 and confirm equal production of matter and antimatter at LHC energies.

Discovery of Rare 'Hypernuclei' Shakes Up Physics at The Large Hadron Collider

Physicists at the Large Hadron Collider have detected over 100 rare hypernuclei, atomic cores containing an unusual flavor of quark, in proton collisions. These hypernuclei, such as hypertriton, are of interest not only for their own sake but also in understanding astrophysical phenomena like neutron stars. By studying the decay products of hypertritons, researchers were able to identify the formation of helium and antihelium nuclei, providing insights into the creation and annihilation of antihelium in space. This discovery also offers a new tool for studying the properties of hypertritons and the quarks that hold baryons together.

Insights into Primordial Matter Phase Changes through Hypernuclei Flow Observations

Physicists at the Relativistic Heavy Ion Collider (RHIC) have observed the directed flow of hypernuclei, rare nuclei containing at least one hyperon, in particle collisions. Hyperons, which contain a “strange” quark, are believed to be abundant in neutron stars. By simulating these conditions in the laboratory, researchers aim to understand the interactions between hyperons and nucleons. The observations, mirroring regular nuclei flow patterns, will help enhance theoretical models of neutron stars.

New insights into hypernuclei flow at RHIC from first measurements.

Physicists at the Relativistic Heavy Ion Collider (RHIC) have observed the directed flow of hypernuclei, which contain at least one "hyperon" in addition to ordinary protons and neutrons. These hyperons contain at least one "strange" quark and are thought to be abundant in the hearts of neutron stars. By comparing the flow of hypernuclei with that of similar ordinary nuclei made only of nucleons, scientists hope to gain insight into interactions between the hyperons and nucleons and understand the inner structure of neutron stars.
