If the Big Bang created equal amounts of matter and antimatter, everything in existence ...

For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an ...

Northwestern physicists created a one-positron quantum cyclotron, resolving individual changes in the antimatter particle’s ...

Antimatter quantum cyclotron: Northwestern scientists trapped a single positron for months at near absolute zero, resolving individual quantum energy steps. This first-ever one-positron quantum ...

Introduction: What is antimatter?Antimatter has appeared here and there, such as in Part 5 where it was mentioned that ...

Forcing a small piece of antimatter into a controlled quantum state may be essential to proving the Standard Model of ...

The explanation behind the universe’s matter-antimatter asymmetry—an apparent violation of a fundamental law of nature known as charge-parity-time (CPT) symmetry—is one of particle physics’ greatest ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists' best current ...

Antimatter.When you hear that, you might think of starship fuel or terrifying weapons from science fiction movies.But in ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Antimatter can produce more energy than anything else we know of, but it’s very fickle. A new field analysis explains what we need in order to progress with antimatter propulsion. While an antimatter ...
