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.

What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That ...

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 ...

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...

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 ...

The standard model of particle physics is often illustrated as a simple grid showing the 17 basic particles (shown above). But an alternative way of visualising it reveals the complex rules that ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

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 ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

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 ...

A proposed funding program for small- and medium-scale projects reveals insights into the science, logistical challenges, and future of particle physics research. Particle physicists have a reputation ...
