Chinese scientists have discovered a new superheavy nucleus of antihyperhydrogen-4 as part of an international project, representatives of the research team announced on August 22 in the pages of the journal Nature.
“We report the observation of an antimatter hypernucleus consisting of an antihyperon, an antiproton, and two antineutrons.” indicated in the authors’ article abstract.
Scientists said the discovery was made while observing ultrarelativistic collisions of heavy ions in the STAR experiment at the Relativistic Heavy Ion Collider. Researchers were able to observe the decay of antimatter born from the ion collision.
Let us recall that one of the modern scientific concepts indicates the presence of an asymmetry between the amount of created matter and antimatter in the Universe that we observe. The asymmetry is that matter dominates around us. The origins of this inequality between matter and antimatter remain unknown to this day.
Physicists have suggested that high-energy collisions of matter nuclei create conditions similar to those in the early state of our Universe (microseconds after the Big Bang). Colliding nuclei produce comparable amounts of matter and antimatter, which can be studied.
