Particle Physics

Initial data from the Muon g-2 experiment have excited particle physicists searching for undiscovered subatomic particles and forces

Muons and electrons might not experience the same fundamental interactions, contrary to Standard Model predictions

Just because a mathematical formula works does not mean it reflects reality

One of the most basic processes in all of nature—a subatomic particle’s transition between discrete energy states—is surprisingly complex and sometimes predictable, recent work shows

The Chinese JUNO experiment will aim to answer a mystery about the particles’ mass

The story of a macroscopic quantum system and a mathematical odyssey

New evidence from neutrinos points to one of several theories about why the cosmos is made of matter and not antimatter

But more data are needed before physicists know for sure

Physicists have found a way the theory might limit the cosmic inflation that is thought to have expanded the early universe

Room-sized “atom waves” could help probe the quantum realm

Exotic new states of matter contain patterns that repeat like clockwork

Cosmic calculations suggest how massive nature’s lightest matter particle could be
