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

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 spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

MACE is a next-generation experiment designed to catch muonium transforming into its antimatter twin, a process that would ...

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 ...

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 ...

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

Here’s what you’ll learn when you read this story: For nearly a century, the magnetic anomaly of the fundamental particle known as a muon has served as a means to test theories against experimental ...

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 ...

Recently analyzed data from BaBar, a high energy physics experiment in the U.S., may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe ...

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 ...
