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.

The CDF Collaboration at Fermilab has confirmed that a subatomic particle called the Bs meson flips between matter and ...

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 ...

Physicists have taken one small-but-consequential step toward measuring the mass of an elusive "ghost particle" called a neutrino — an achievement that could poke a significant hole in the Standard ...

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 ...

On Monday, the Society of Physics Students, or SPS, welcomed Helen Quinn — a renowned particle physicist — to deliver the Howard L. Schultz Sr. Price Lecture. During the talk, Quinn spoke on her ...
