Through the “Snowmass” process, US particle physicists thoroughly considered the field’s most compelling unanswered questions and ways to realistically answer them.

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.

Three SLAC scientists will receive Early Career Research Program grants from the U.S. Department of Energy for research to boost the peak power of X-ray laser pulses, model catalytic chemical reactions and build better simulations of particle collisions at CERN's...
