Researchers in the United States’ Fermilab moved the final subdetector for Mu2e into the ...

The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists ...

A high-precision experiment is hunting for a forbidden particle flip that could expose new physics hiding in plain sight.

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

NEW YORK (AP) — Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely — but that’s still good news for the laws of physics as we ...

ANN ARBOR, Mich.–The results of a high-profile Fermilab physics experiment involving a University of Michigan professor appear to confirm strange 20-year-old findings that poke holes in the standard ...

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 ...
