Particle Physics

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

The theory, which emerged in the 1970s as a way to unify the fundamental forces of nature, has profoundly shaped the landscape of particle physics

A proposed experiment to swap fundamental properties between photons carries profound implications for our understanding of reality itself

Physicists attempting to unify the theories of  gravity and quantum mechanics have long thought practical experiments were out of reach, but new proposals offer a chance to test the quantum nature of gravity on a tabletop

High-pressure hydrogen materials could be a step toward a new era of superconductivity
