Mapping out the properties of antimatter

Why does anything exist? That is really the fundamental question we try to answer through high-precision studies of antimatter. All matter that builds up the universe we see should really have been annihilated through contact with it mirror image – antimatter. Clearly, this has not happened, which is one of the great still unsolved mysteries of Physics.

How similar are antihydrogen and hydrogen?

Bioluminescence is the production and emission of light by a living organism as the result of a chemical reaction during which energy is converted to light energy. This is a natural phenomenon and it is most common in deep sea living creatures.

Antimatter spectroscopy

First measurements of the line-shape of the 1s-2s in the antihydrogen atom are reported in a paper published in Nature, by the ALPHA collaboration, where Fysikum is a partner. The line shape agrees with ordinary hydrogen to a relative precision of 2x10^-12, and thus puts an upper limit to the possible violation of matter-antimatter symmetries.
