Mirror image: Fundamental symmetry in nature confirmed using CERN Large Collider

The existence of a fundamental symmetry in nature has been confirmed by measuring particle mass and electric charge using the CERN Large Hadron Collider. Researchers say it will help determine which theory on the laws of the universe is most plausible.

The study, conducted by researchers at Brazil’s São Paulo University (USP) and the University of Campinas, determined that there is a symmetry between the nuclei of particles and their antiparticles in terms of charge, parity, and time. The research was published in the journal Nature Physics.

The experiment was part of an investigation to detect differences between the ways in which protons and neutrons join in nuclei while their antiparticles form antinuclei.
