Mirror symmetry validated for proton and its antimatter twin

Nature, Published online: 05 January 2022; doi:10.1038/d41586-021-03798-4

A comparison of the charge-to-mass ratio for the proton and the antiproton has been performed with record-breaking precision — the best such test yet for a mirror-like symmetry that relates matter and antimatter.
