The standard model of particle physics works really well, but it can't explain why the universe exists. Something is missing, ...
For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an ...
After trapping a positron for the first time, physicists plan to use the resulting data to look for answers to one of ...
The universe owes its existence to a tiny mismatch, but one of the greatest consequences imaginable. In its earliest moments, ...

You can’t hold antimatter in your hand or even in a regular laboratory apparatus. As soon as antimatter meets matter, the two ...
Why is the universe the way it is? A long-overlooked particle might have given matter an edge over antimatter in the split-seconds after the Big Bang, which researchers say “could transform our ...
Northwestern physicists created a one-positron quantum cyclotron, resolving individual changes in the antimatter particle’s ...
A “forgotten” particle could answer the mystery of why we exist, say physicists. A new theory on the birth of the cosmos has ...
