A team of astronomers may have detected the gamma-ray signature produced when antimatter particles, or positrons, collide ...

The Big Bang created equal amounts of matter and antimatter. So, why is there so much more matter than antimatter in the Universe? Irfu is participating in the preparation of Hyper-Kamiokande, a ...

Physicists have successfully transported antimatter by truck for the first time — a milestone that allows them to study the elusive material with unprecedented precision and could eventually help to ...

A small amount of antimatter took to the road on Tuesday, representing the first time any quantity of the world’s most expensive, volatile and rare substance has been moved. The breakthrough opens the ...

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 ...

Why didn’t the universe annihilate itself moments after the big bang? A new finding at Cern on the French-Swiss border brings us closer to answering this fundamental question about why matter ...

On March 24, at the annual Rencontres de Moriond conference taking place in La Thuile, Italy, the LHCb collaboration at CERN reported a new milestone in our understanding of the subtle yet profound ...

Our universe is filled with particles, such as electrons and protons, which make up all the stuff on our planet and beyond: animals, plants, people, planets, asteroids, stars, gas clouds, and galaxies ...

Discover why the universe favors matter and antimatter. New findings from the Tevatron hint at mysteries in particle behavior. As opposed to simply energy, the universe is also made of stuff. Not a ...

I'm in the middle of a couple of posts about the matter-antimatter asymmetry of the universe and have found that I keep referring to things I posted back on my old blog a long time ago. This became so ...
