Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics.

A forthcoming upgrade to the IceCube detector will provide deeper insights into the elusive particles. Underneath the vast, frozen landscape of the South Pole lies IceCube, a gigantic observatory ...

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 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 ...

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 ...

Although scientists have yet to find the spooky stuff, they aren’t completely in the dark. There are a lot of things scientists don’t know about dark matter: Can we catch it in a detector? Can we make ...

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 ...

Scientists around the world are testing ways to further boost the power of particle accelerators while drastically shrinking their size. At least when it comes to particle accelerators, bigger is ...

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 ...

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 ...

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

The 2013 documentary Particle Fever follows physicists from the start-up of the LHC through the discovery of the Higgs boson. Where are those physicists now? Physicist Monica Dunford remembers when ...
