A possible explanation for the lightness of neutrinos could help answer some big questions about the universe. Mass is a fundamental property of matter, but there’s still a lot about it we don’t ...

Meet the world’s deepest underground physics facilities. A constant shower of energetic subatomic particles rains down on Earth’s surface. Born from cosmic ray interactions in the upper atmosphere, ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

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 ...

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 ...

A team of young scientists paused their new physics searches to develop an innovative machine-learning tool, which is now helping them narrow in on a rare and messy decay of the Higgs boson. Physicist ...

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges. Discussing her decades-spanning career, photographer Annie Leibovitz ...

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 ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

One of the latest discoveries from the LHC takes the properties of photons beyond what your electrodynamics teacher will tell you in class. Professor Anne Sickles is currently teaching a laboratory ...

The Large Synoptic Survey Telescope will be named for an influential astronomer who left the field better than she found it. The Large Synoptic Survey Telescope, a flagship astronomy and astrophysics ...

Writer Chetna Krishna follows CERN’s “coolest” transport, a test of a system to ship stored antimatter across the continent. I reach CERN’s Antimatter Factory at 8 a.m. sharp. I’m here at the ...
