Production and detection of cold antihydrogen atoms

https://www.nature.com/articles/nature01096

As for the analysis, anti-particles are pretty much the same as their mirror particles save for some mirrored attribute(s), so charged antimatter particles carry the same charge as matter particles, but of opposite sign. An antiproton is negatively charged and an antielectron (positron) is positively charged.

Looking at particle tracks they'll see matching masses but curves in charged fields going in opposite directions.

Uncharged particles have some other mirrored attribute, so again "it's just like regular Alice only it's a mirror Alice wrt { X? }"
