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 ...

Matter and antimatter behave differently. Scientists hope that investigating how might someday explain why we exist. One of the great puzzles for scientists is why there is more matter than antimatter ...

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 ...

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 ...

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, ...

The average banana produces a particle of antimatter roughly once every 75 minutes. US-based scientists and students working on research and experiments with the Large Hadron Collider contribute to a ...

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 ...

Amy Catanzano bridges the worlds of poetry and science. In April 2018, Amy Catanzano sat in her loaned office at the Simons Center for Geometry and Physics at Stony Brook University in New York, ...

Not only are we made of fundamental particles, we also produce them and are constantly bombarded by them throughout the day. Fourteen billion years ago, when the hot, dense speck that was our universe ...

Over time, particle physics and astrophysics and computing have built upon one another’s successes. That coevolution continues today. In the mid-twentieth century, particle physicists were peering ...

Quantum physics says everything is made of particles, but what does that actually mean? “Is he a dot or is he a speck? When he's underwater, does he get wet? Or does the water get him instead? Nobody ...
