}A new comparison of the antiproton–proton charge-to-mass ratios has been completed. The measured ratio of charge-to-mass ratios for the antiproton and proton is 1.000 000 001 5 ± 0.000 000 001 1. Comparing the cyclotron frequencies of a single p̄ and p in a Penning trap improves upon the accuracy of earlier techniques by a factor of 45,000. This comparison is the most accurate mass spectroscopy of particles of opposite charge in a Penning trap and the most accurate test of the CPT theorem with…

This work shows that hyperbolicity can be computed in time O(2 +n+m) (m being the number of graph edges) while at the same time, unless the SETH fails, there is no 2n-time algorithm.
