Theoretical physics

Constellations illustrates the many-worlds interpretation of quantum mechanics—with a love story.

A unique groundbreaking ceremony marked the start of construction of the Long-Baseline Neutrino Facility – future home of the Deep Underground Neutrino Experiment, which promises to shed new light on how the universe works and why matter exists.

How did the proton, photon and other particles get their names?

H. Pierre Noyes, the first director of SLAC's Theory Group, died in Stanford on Sept. 30, 2016, at age 92. Noyes, a theoretical physicist, leaves behind a legacy of distinctive academic work and activism.

How can we measure the worth of scientific knowledge? Economic analysts give it a shot.

Scientists furthered studies of the Higgs boson, neutrinos, dark matter, dark energy and cosmic inflation and continued the search for undiscovere

What have scientists learned in five years of studying cosmic rays with the Alpha Magnetic Spectrometer experiment?

Four physicists discuss Higgs boson research since the discovery.

What are parallel universes, and why do we think they might exist?

The prize, shared with Sekazi Mtingwa and Anton Piwinski, honors theoretical work that helped sharpen the focus of beams at a wide variety of particle accelerators.

Participants of SLAC’s summer school learned about the next generation of collider physics through lectures, topical conference talks, student projects, poster sessions and tours.

The scientists develop methods to study neutrinos from star explosions and search for unknown particles and forces with possible ties to dark matter.
