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.
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.
Berkeley Lab has a long history of participating in neutrino experiments and discoveries in locations ranging from a site 1.3 miles deep at a nickel mine in Ontario, Canada, to an underground research site near a nuclear power complex northeast of Hong Kong, and a neutrino observatory buried in ice near the South Pole.
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.
In this Q&A, Sinéad Griffin, a staff scientist in Berkeley Lab’s Materials Sciences Division and Molecular Foundry, shares her thoughts on her search for light dark matter, the ultimate materials design challenge, and Berkeley Lab’s collaborative “team science” culture.
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.
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.
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.
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.
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.
