Theoretical physics

Theorists from the Institute for Advanced Study have proposed a way forward in the quest to test string theory.

Why are there three almost identical copies of each particle of matter?

SLAC has led the development and implementation of a variety of upgrades to the ATLAS experiment to match the increased discovery potential of an LHC now operating at record proton collision energies.

Noether's theorem is a thread woven into the fabric of the science.

Either Supersymmetry will be found in the next years of research at the Large Hadron Collider, or it isn’t exactly what theorists hoped it was.

The European Physical Society honors Bjorken’s theoretical work on the parton structure of the proton, which contributed to the development of a theory of the strong nuclear force.

Honored for early theoretical predictions that helped elucidate the nature of the strong force and the structure of the proton, he is still shaking things up today.

Experiments have helped explain some of the imbalance between matter and antimatter in the universe, but not all of it. Now a SLAC theorist and his colleagues have laid out a possible method for determining if the Higgs boson is...

Physicists have good reason to believe 85 percent of the matter in the universe is currently undetectable. But not being able to see it didn’t keep students at the 42nd SLAC Summer Institute from learning about it.

The Particle Physics Project Prioritization Panel’s report, released today, recommends a strategic path forward for US particle physics.

The Particle Physics Project Prioritization Panel’s recommendations will set the course for the future of particle physics in the United States.

SLAC recently hosted a forward-looking group of theoretical and experimental particle physicists. Their purpose: Follow the science to determine what a post-LHC collider could teach us about the universe.
