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.

Berkeley Lab Scientists Contribute to New Exploration of Higgs Boson Interactions

A new analysis, featuring important contributions by Berkeley Lab scientists, strongly supports the hypothesis that the Higgs boson interacts with muons, which are heavier siblings of electrons and the lightest particles yet to reveal evidence for these interactions.

An Innovative Pattern: Scientists Rewrite Rules for 2D Electronics

Scientists at Berkeley Lab and UC Berkeley have developed a new technique for fabricating tiny circuits from ultrathin materials for next-generation electronics, such as rewritable, low-power memory circuits.

Shhh! These Tests Will Enable a Quieter Search for Dark Matter

The subatomic world just got a lot quieter for the LUX-ZEPLIN (LZ) dark matter experiment. The LZ collaboration has completed 1,200 tests that describe the levels of radioactive decay of the LZ detector components and help to ensure a low level of background “noise” from unwanted particle signals.

Berkeley Team Plays Key Role in Analysis of Particle Interactions That Produce Matter From Light

Researchers at Berkeley Lab played a key role in an analysis of data from the world’s largest particle collider that found proof of rare, high-energy particle interactions in which matter was produced from light.

CERN’s Large Hadron Collider Creates Matter From Light

The Large Hadron Collider transforms matter into energy and then back into different forms of matter. But on rare occasions, it can skip the first step and collide pure energy – in the form of electromagnetic waves. Now, scientists have discovered particles of light merging and transforming into W bosons, confirming that at high enough energies, forces that seem separate in our everyday lives are united.

Lead Lab Selected for Next-Generation Cosmic Microwave Background Experiment

The largest collaborative undertaking yet to explore the relic light emitted by the infant universe has taken a step forward with the U.S. Department of Energy’s selection of Lawrence Berkeley National Laboratory (Berkeley Lab) to lead the partnership of national labs, universities, and other institutions that will carry out the DOE roles and responsibilities for the effort. This next-generation experiment, known as CMB-S4, or Cosmic Microwave Background Stage 4, is planned as a joint DOE and NSF project.

Lab Researcher and Physics Undergrad Shares Poster Project Honoring Black Physicists

Inspired by the nation’s grappling with issues of race and racial discrimination, UC Berkeley physics major and Berkeley Lab student assistant Ana Lyons turned to art as a way to contribute to the conversation.

3 Awards Will Support Accelerator R&D for Medical Treatment, Miniaturization, and Machine Learning

U.S. Department of Energy awards announced in July will advance Lawrence Berkeley National Laboratory (Berkeley Lab) R&D to develop a more effective and compact particle-beam system for cancer treatment, improve particle-beam performance using artificial intelligence, and develop a high-power, rapid-fire laser system for both tabletop and large-scale applications.
