The NSF-DOE Vera C. Rubin Observatory, a major new scientific facility jointly funded by the US National Science Foundation ...

Yesterday, at the annual Rencontres de Moriond conference taking place in La Thuile, Italy, the LHCb collaboration at CERN reported a new milestone in our understanding of the subtle yet profound ...

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 particles we’re made of About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential ...

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 ...

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 are notoriously aloof, but it’s not entirely their fault. Neutrinos are some of the most abundant particles in the universe, and they are everywhere. Every second, more than 6 trillion ...

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 ...

Nearly 75 years after the puzzling first detection of the kaon, scientists are still looking to the particle for hints of physics beyond their current understanding.

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges.

With big outstanding questions and little hints of new physics, physicists are now rethinking some of their most fundamental assumptions. For centuries, scientists thought the universe was filled with ...
