A 16-parts-per-trillion measurement of the antiproton-to-proton charge–mass ratio

The standard model of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter in the observable universe 1 , which inspires experiments to compare the fundamental properties of matter/antimatter conjuga...
