Observations of extremely rare subatomic particle actions have allowed scientists to put one of the most stringent limits yet on the reigning theory of particle physics. Subscribe to read this story ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

This lesson utilizes an adaptation of the board game Subatomic: An Atom Building Game to help students learn about the different parts that make up an atom. During their turn, players can choose to ...

A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

One hundred years ago, physicists including Max Born, Niels Bohr, Werner Heisenberg, and Erwin Schrödinger theorized the foundations of quantum mechanics, unlocking atomic and subatomic secrets, ...

In physical sciences, subatomic particles can be composite particles, such as the neutron and proton, or elementary particles. Based on the standard model, elementary particles are not made of other ...
