Swift Summary
- Researchers at the Large Hadron Collider (LHC) have observed evidence of antihyperhelium-4, the heaviest antimatter nucleus ever created in a physics laboratory.
- The new finding surpasses previous antimatter records set by researchers from Brookhaven National Laboratory’s RHIC facility in new York, who reported creating antihyperhydrogen-4 in 2024 during experiments with energetic lead ion collisions.
- This discovery marks an importent milestone in understanding exotic forms of matter and their properties under extreme conditions.
