Simple matter, complex antimatter, and added strangeness

Having reported on ways to store and use large amounts of simple antimatter—positrons—we'll now turn our attention to more complex forms of antimatter. While creating positrons is a fairly straightforward process, creating more complex interactions between antiparticles in a controlled fashion is a much more complicated task.

The first talk in this part of the symposium looked at the production of the simplest possible anti-element, antihydrogen. Atomic hydrogen is simple, consisting of one electron orbiting a single proton. Its antimatter equivalent is then a positron orbiting an antiproton. The main hurdle to making it is getting enough of each ingredient (positrons and antiprotons) together in the same place for them to react and form an antiatom.
