The discovery of the new antihypernucleus could help scientists better understand the state of the universe just a millionth of a second after the Big Bang.

Charge-parity violation is thought to explain why there’s more matter than antimatter in the universe. Scientists just spotted it in a new place.

Matter and antimatter should have completely wiped each other out eons ago, leaving the Universe a very empty place.

Physicists at CERN may have glimpsed an elusive particle, 'toponium', never observed before. This discovery could ...

Experiments in high-energy physics have demonstrated the complete symmetry between particles and antiparticles. A novel theory of the universe that takes this basic symmetry into account is advocated ...

particles and antiparticles, such as electrons and positrons, are described as quantum fields. They interact through other force-fields, such as the electromagnetic force that binds charged particles.

Besides, particles and anti-particles produced in dark matter collisions ... Preliminary AMS-02 data published yesterday show that high energy antiparticles are arriving to Earth from all directions.

then one might expect equal amounts of matter and antimatter to result from a synthesis which employs equal numbers of elementary particles and antiparticles (probably electrons, positrons ...

Heaviest known elementary particles and their antimatter counterparts are detected after nuclear smash-ups at the Large Hadron Collider.
