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.

SLAC particle theorist Lance Dixon has been named co-winner of the 2014 J.J. Sakurai Prize for Theoretical Particle Physics, awarded each year by the American Physical Society.

The Nobel Prize in physics has been awarded to theorists Peter Higgs and Francois Englert to recognize their work developing the theory of what is now known as the Higgs field. U.S. scientists played a significant role in advancing their...

Three theoretical physicists have taken an important step toward eliminating theoretical ambiguities from the staggeringly complicated mathematics used to explore the interactions of quarks, the tiniest known bits of matter inside protons and neutrons, and gluons, the enigmatic particles responsible...

For the 41st annual Particle Physics & Astrophysics Department’s SLAC Summer Institute (SSI), organizers introduced a successful new feature.

Theorists from the Kavli Institute for Particle Astrophysics and Cosmology are helping dark matter sleuths decide where to start their search.

Scientists analyzing data from theScientists analyzing data from the BaBar experiment, which operated at SLAC between 1999 and 2008, recently published the results of a search for signs of invisible particles: exotic bits of matter that interact so weakly with...

Menlo Park, Calif. — Time marches relentlessly forward for you and me; watch a movie in reverse, and you’ll quickly see something is amiss.

The search for dark matter runs deep with physicists Blas Cabrera and Bernard Sadoulet, who have chased this mystery far underground and will be recognized for their work as joint recipients of the 2013 W.K.H. Panofsky Prize in Experimental Particle...
