The antineutron is the antiparticle of the neutron with symbol n. It differs from the neutron only in that some of its properties have equal magnitude but opposite sign. It has the same mass as the neutron, and no net electric charge, but has opposite baryon number (+1 for neutron, −1 for the antineutron). This is because the antineutron is composed of antiquarks, while neutrons are composed of quarks. The antineutron consists of one up antiquark and two down antiquarks. (Wikipedia).
ALPHA experiment: an improved limit on the charge of antihydrogen
Researchers working on the ALPHA experiment at CERN's Antiproton Decelerator (AD) have published the most accurate measurement yet of the electric charge of antihydrogen atoms in a paper in the journal Nature. In this video, ALPHA spokesperson, Jeffrey Hangst, explains the significance of

ALPHA Experiment at CERN cools antimatter using laser light for the first time
The ALPHA collaboration at CERN has succeeded in cooling down antihydrogen atoms – the simplest form of atomic antimatter – using laser light. The result opens the door to considerably more precise studies of the internal structure of antihydrogen and of how it behaves under the influenc

7 Subatomic Stories: Antimatter
Of all of the claims of modern physics, perhaps the most amazing is that for every kind of known matter, there is a cousin version called antimatter. Antimatter is the opposite of ordinary matter and will annihilate into pure energy when it encounters matter. In episode 7 of Subatomic Sto

What Makes Antimatter So Special?! (animations by SEJL)
It's pretty well known that matter annihilates when it comes into contact with antimatter. Unfortunately, not enough people know why this happens, what its consequences are, and what it means in the grand scheme of the universe. That’s what this video is all about! Huge thanks to Super E
