NSF–DOE Vera C. Rubin Observatory, funded by the US National Science Foundation and US Department of Energy's Office of ...

The experiment's third and final result, based on the last three years of data, is in perfect agreement with previous results ...

With big outstanding questions and little hints of new physics, physicists are now rethinking some of their most fundamental ...

Symmetry receives funding through the US Department of Energy.

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning—but many researchers are not giving up on it yet. The Standard Model of particle physics is ...

An overly plump atomic nucleus just can’t keep itself together. When an atom has too many protons or neutrons, it’s inherently unstable. Although it might sit tight for a while, eventually it can’t ...

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behavior of particles called baryons. “The reason why it took longer to observe CP violation in baryons than in mesons is down ...

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...

The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible ...
