SLAC experimentalists and theorists collaborate to develop critical detector components, data analysis tools, and theoretical models for the HL-LHC upgrade, which will investigate the Higgs boson and pursue physics beyond the Standard Model.

They’ll work on experiments searching for dark matter and physics beyond the Standard Model of particle physics to push our understanding of what makes up the universe.

The ATLAS experiment measured more than expected of a trio of particles in the aftermath of proton collisions. The results will refine physicists’ understanding of our universe at the subatomic level.

The ATLAS and CMS experiments have observed a process 4,000 times rarer than the production of Higgs bosons.

Bernhard Mistlberger will receive the APS's 2023 Henry Primakoff Award for Early-Career Particle Physics for his work on precision Standard Model calculations.

From the invisible world of elementary particles to the mysteries of the cosmos, recipients of this prestigious award for early career scientists explore nature at every level.

Edward Hohenstein, Emma McBride and Caterina Vernieri study what happens to molecules hit by light, recreate extreme states of matter like those inside stars and planets, and search for new physics phenomena at the most fundamental level.

During the last four years, LHC scientists have filled in gaps in our knowledge and tested the boundaries of the Standard Model.

A specialized measuring machine at SLAC is helping scientists build precise detectors for the ATLAS experiment.

Today the ATLAS collaboration, which includes SLAC physicists, announced with the CMS collaboration the joint discovery of the Higgs boson transforming into bottom quarks as it decays.

A team of electrical designers develops specialized microchips for a broad range of scientific applications, including X-ray science and particle physics.

The event attracted 124 participants and explores the successes and challenges of the theory that describes subatomic particles and fundamental forces.
