The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

In 2023, a subatomic particle smashed into the Mediterranean Sea with enough energy to rattle the foundations of physics. The particle was a neutrino, a fundamental subatomic particle that usually ...

Physicists have found provocative evidence that a subatomic particle behaves in a way that cannot be explained by the prevailing model of how matter works on the smallest scale. If confirmed, the ...

In the alphabet-soup world of subatomic physics, only one letter was missing. The equations of quantum theory had indicated the existence of 17 pairs of basic “building blocks”—particles and ...

The Nobel-Prize-winning physicist Peter Higgs has died at age 94. He was celebrated for his work on the mass of subatomic particles. Today the University of Edinburgh announced the death of the Nobel ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...
