The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the ...

The new subatomic particle is called the beauty-lambda baryon.It belongs to a group of particles known as baryons, which include protons and neutrons. These particles are made of three quarks.

Neutrinos are ghostly subatomic particles that can travel in a straight line for billions of light-years, passing unhindered through galaxies, stars and anything else in their path.

Most exotic hadrons, which are subatomic particles, are made up of two or three elemental particles known as quarks. The strong force is one of four forces known in the universe, ...

The discovery is exciting, though, because it's the first theoretical proof that it's possible to fuse subatomic particles together in ways that release energy, Karliner said.

Baryons are subatomic particles made up of quarks. Protons and neutrons are the most common baryons. Quarks are even smaller particles that come in six types, ...
