Hidden worlds of fundamental particles - PHYSICS

The standard model, physicists' current theory of matter and its interactions, has stood up to several decades of tests at high-energy particle colliders. But we know that it cannot be the complete description of the universe. The standard model doesn't explain dark matter, the dominance of matter over antimatter, or the energy scales of nature's major forces.

Physicists David Curtin and Raman Sundrum explain how hidden sectors—additional particles and forces that interact only rarely with the constituents of the standard model—can address all three big mysteries.
