Scientists involved in experiments at the Large Hadron Collider have discovered the world’s heaviest nucleus. The existence of Antihyperhelium 4 has been confirmed.
“Members of the ALICE (A Large Ion Collider Experiment) collaboration working at the Large Hadron Collider have detected traces of an “antimatter” analog of hyperhelium 4 – two antiprotons, an antineutron and an anti-lambda hyperon (a particle made up of two first-generation quarks, the fundamental elements of matter),” the Rosatom Country corporate publication reported.
It explained that antimatter is a mirror version of ordinary matter, in which the particles have opposite electric charges and possess a number of distinctive quantum properties.
“The experiment studied the collision of heavy lead ions, which create extreme conditions similar to those immediately after the Big Bang. The researchers analyzed the data using machine learning techniques and concluded that there is a high probability that antihyperhelium-4 exists,” the report said.
The experiments at the Large Collider involve 1,500 scientists from 37 countries, including representatives of the National Nuclear Research University MEPhI and the All-Russian Research Institute of Experimental Physics.
