As 'Run 3' begins, CERN touts discovery of exotic particles

The physics lab that's home to the world's largest atom smasher announced on Tuesday the observation of three new "exotic particles" that could provide clues about the force that binds subatomic particles together.

Physicists announce first results from Daya Bay's final dataset

Over nearly nine years, the Daya Bay Reactor Neutrino Experiment captured an unprecedented five and a half million interactions from subatomic particles called neutrinos. Now, the international team of physicists of the Daya ...

Nanoscale currents improve understanding of quantum phenomena

Besides charge, subatomic particles like electrons also carry a property called spin, which is responsible for magnetism. Novel proposals to use spin to store information have emerged in recent years with the promise to be ...

Quantum mechanics could explain why DNA can spontaneously mutate

The molecules of life, DNA, replicate with astounding precision, yet this process is not immune to mistakes and can lead to mutations. Using sophisticated computer modeling, a team of physicists and chemists at the University ...

Lasers trigger magnetism in atomically thin quantum materials

Researchers have discovered that light—in the form of a laser—can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons. These subatomic particles have an ...

Subatomic particle

In physics, subatomic particles are the particles composing nucleons and atoms. There are two types of subatomic particles: elementary particles, which are not made of other particles, and composite particles. Particle physics and nuclear physics study these particles and how they interact.

Elementary particles of the Standard Model include:

Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nuclei of helium-4 is composed of two protons and two neutrons. Composite particles include all hadrons. These, in turn, are composed of baryons (e.g., protons and neutrons) and mesons (e.g., pions and kaons).

There are hundreds of known subatomic particles. Most are either the result of cosmic rays interacting with matter, or have been produced by scattering processes in particle accelerators.[citation needed]
