What Is the New Subatomic Particle? 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.

Discover the fascinating world of particle physics — the most fundamental building blocks of the universe and the forces that connect them.

At Fermilab, US physicists are refining their measurements of this subatomic particle—which has major implications for the Standard Model.

Predicting the properties of subatomic particles before their experimental discovery has been a big challenge for physicists.

How particle detectors capture matter’s hidden, beautiful reality Old and new detectors trace the whirling paths of subatomic particles ...

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.

The subatomic particle that has a negative charge is the electron. Out of the three subatomic particles that compose an atom, the electron has the smallest mass.

The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their understanding of physics ...

Physics Scientists create particles that remember their pasts The particle is called an anyon and was theorized by physicists decades ago ...

Muons are subatomic particles that are similar to electrons but around 200 times heavier. At high energy, they can easily travel through hundreds of yards of solid rock.

By measuring the momentum of the pions, researchers can get a picture of the density of the thing the photon bounced off of—in this case, the subatomic particles making up the ion’s nucleus.
