Missing Baryons Found in Far-Out Reaches of Galactic Halos

Researchers have channeled the universe’s earliest light – a relic of the universe’s formation known as the cosmic microwave background (CMB) – to solve a missing-matter mystery and learn new things about galaxy formation. Their work could also help us to better understand dark energy and test Einstein’s theory of general relativity by providing new details about the rate at which galaxies are moving toward us or away from us.

U.S. Magnet Development Project for CERN Particle Collider Upgrade Moves Forward

The U.S. Department of Energy has formally approved a key milestone in the High-Luminosity LHC Accelerator Upgrade Project being carried out at eight U.S. institutions, including the DOE’s Berkeley Lab.

Tantalizing Signs of Phase-change ‘Turbulence’ in RHIC Collisions

A new analysis of collisions conducted at different energies, with contributions by Berkeley Lab scientists, shows tantalizing signs of a critical point – a change in the way that quarks and gluons, the building blocks of protons and neutrons, transform from one phase to another.

Researchers Hunt for New Particles in Particle Collider Data

Berkeley Lab researchers participated in a study that used machine learning to scan for new particles in three years of particle-collision data from CERN’s ATLAS detector.

Applying Quantum Computing to a Particle Process

A team of researchers at Berkeley Lab used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments, such as those that occur at CERN’s Large Hadron Collider.

Study: X-Rays Surrounding ‘Magnificent 7’ May Be Traces of Sought-After Particle

A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Scientists Say Farewell to Daya Bay Site, Proceed with Final Data Analysis

The Daya Bay Reactor Neutrino Experiment collaboration – which made a precise measurement of an important neutrino property eight years ago, setting the stage for a new round of experiments and discoveries about these hard-to-study particles – has finished taking data. Though the experiment is formally shutting down, the collaboration will continue to analyze its complete dataset to improve upon the precision of findings based on earlier measurements.

Know When to Unfold ’Em: Study Applies Error-Reducing Methods from Particle Physics to Quantum Computing

Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at Berkeley Lab has successfully adapted and applied a common error-reduction technique to the field of quantum computing.

A Major Milestone for an Underground Dark Matter Search Experiment

Crews working on the largest U.S. experiment designed to directly detect dark matter completed a major milestone last month, and are now turning their sights toward startup after experiencing some delays due to global pandemic precautions.

VIDEO: Dark Matter Day Q&A with LUX-ZEPLIN Spokesperson Kevin Lesko

Kevin Lesko, a spokesperson for the LUX-ZEPLIN (LZ) dark matter experiment and senior physicist at Berkeley Lab, shares his insights about the mysteries of dark matter, what we know about it, and what we hope to learn about it from LZ, in this Q&A interview at Sanford Lab.
