Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same ...
After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.
Red lines show the disintegration of a B-sub-s into two muons in the CMS camera at the Large Hadron Collider. Yello, green and blue are used to denote particles other than muons. Purdue University ...
Quantum electrodynamics (QED) is the most rigorously tested quantum field theory of the standard model of particle physics 1. It describes the fundamental electromagnetic interactions of particles and ...
What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That ...
A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...
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 ...
