The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force.

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

That property is predicted by the standard model of particle physics, the theory that describes particles and forces on a subatomic level. In fact, it’s the most precise prediction made by that ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

Dark matter, although not visible, is believed to make up most of the total mass of the universe. One theory suggests that ...

Final results from a long-running U.S. experiment have revealed that a tiny particle continues to act strangely, which scientists say is good news for our current understanding of the laws of physics.

We may already have had our first-ever encounter with dark matter, according to researchers who say a mysteriously ...

New subatomic particle discovery may challenge the Standard Model and explain why matter dominates over antimatter in the universe. The post New Subatomic Particle Discovery Could Rewrite Physics ...

Final results from a long-running U.S.-based experiment show a tiny particle continues to act strangely -- but that’s still good news for the laws of physics as we know them.
