An analysis using LHC data verifies the existence of an exotic four-quark hadron.

From accelerators unexpectedly beneath your feet to a ferret that once cleaned accelerator components, symmetry shares some lesser-known facts about particle accelerators.

Researchers from the BICEP2 collaboration have announced the first direct evidence supporting the theory of cosmic inflation. Their data also represent the first images of gravitational waves, or ripples in space-time. These waves have been described as the "first tremors...

More than 150 US universities and laboratories are engaged in particle physics research and technology innovation, playing important roles in the Higgs boson and cosmic inflation discoveries—and the many more revelations still to come.

A cooperative agreement with Palo-Alto based CPI opens the door to routine commercial manufacturing of these powerful vacuum tube devices, which convert electron beams into microwaves that are used to accelerate subatomic particles.

Particle Fever is a documentary that follows scientists involved in research at the Large Hadron Collider, including the ATLAS Experiment in which SLAC participates. The film opens this week in select theaters across the United States.

In a SLAC test facility, scientists have set the stage for an experiment that mimics what happens when incredibly energetic cosmic ray particles hit our atmosphere. While the experiment is part of ANITA, which sends balloon-borne instruments into the upper...

Editors of the journal Science, published by the American Association for the Advancement of Science, have selected their annual Top 10 Science Breakthroughs of the Year. On the list: Work by SLAC researchers pinning down the origin of cosmic rays.

How is it possible to look at the earliest moments of the universe?

SLAC's Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) recently hosted many of the top scientists in the field to discuss the most important questions to confront in the coming decade.

SLAC and Stanford physicists played a key role in monitoring and analyzing the brightest gamma ray burst ever measured, and suggest that its never-before-seen features could call for a rewrite of current theories.

Scientists in SLAC's Integrated Circuits Department reach a new frontier in ultrafast X-ray science with intricately designed signal-processing chips that translate particles of light into bits of data.
