A test of charge-parity-time invariance at the atto-electronvolt scale
We developed a novel fast measurement procedure for cyclotron frequency comparisons of two individual particles in a Penning trap, which enabled us to compare the charge-to-mass ratio of the proton and the antiproton with a fractional precision of 69 parts per trillion. To date this is the most prec...

| description | We developed a novel fast measurement procedure for cyclotron frequency comparisons of two individual particles in a Penning trap, which enabled us to compare the charge-to-mass ratio of the proton and the antiproton with a fractional precision of 69 parts per trillion. To date this is the most precise test of charge-parity-time invariance using baryons. Our measurements were performed at cyclotron frequencies of about 30 MHz, which means that charge-parity-time symmetry holds at the atto-electronvolt scale. |
