  • 90 Years of Neutrino Science90 Years of Neutrino Science
    A collection of images from past, present, and pending neutrino science experiments, including: Daya Bay, DUNE at LBNF, the Homestake experiment, IceCube, KamLAND, ProtoDUNE and SNO. Displayed in the background is the typed text of a letter that physicist Wolfgang Pauli had written on Dec. 4, 1930, postulating the existence of the neutrino. They come in three flavors and can transform among these different types as they travel. They pass through most matter undetected and uninterrupted. Tens of trillions of them are passing through your body in the time it takes to read this sentence. But don’t worry – they… Read more »

    A wheel-shaped muon detector is part of an ATLAS particle detector upgrade at CERN. A new study applies “unfolding,” or error-correction techniques used for particle detectors, to problems with noise in quantum computing. (Credit: Julien Marius Ordan/CERN) Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has successfully adapted and applied a common error-reduction technique to the field of quantum computing. In the world of subatomic particles and giant particle detectors, and distant galaxies and giant telescopes, scientists have learned to… Read more »
  • A Major Milestone for an Underground Dark Matter Search ExperimentA Major Milestone for an Underground Dark Matter Search Experiment

(Credit: Nick Hubbard/Sanford Lab) 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. U.S. Department of Energy officials on Sept. 21 formally signed off on project completion for LUX-ZEPLIN, or LZ: an ultrasensitive experiment that will use 10 metric tons of… Read more »

    A display of a candidate Higgs boson event at CERN’s ATLAS experiment in which a Higgs boson decays into two muons. The muons appear as red tracks in this rendering. (Credit: ATLAS collaboration) Since the discovery of the Higgs boson in 2012 based on data from the ATLAS and CMS experiments at CERN’s Large Hadron Collider (LHC), scientists have been gathering new data on the Higgs particle and its associated Higgs field to understand how – and whether – it interacts with specific types of other particles. The Higgs particle plays a central role in the Standard Model of particle physics,… Read more »

The subatomic world just got a lot quieter for the LUX-ZEPLIN (LZ) dark matter experiment. Currently being assembled on the 4850 Level, 4,850 feet below the surface at the Sanford Underground Research… Read more »
  • Berkeley Team Plays Key Role in Analysis of Particle Interactions That Produce Matter From LightBerkeley Team Plays Key Role in Analysis of Particle Interactions That Produce Matter From Light
    This image shows a reconstruction of a particle event at CERN’s ATLAS detector that produced W bosons from photons, which are particles of light. (Credit: ATLAS collaboration) Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (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. Simone Pagan Griso, a Berkeley Lab physicist and Divisional Fellow who coordinated the efforts of the Berkeley Lab team, said his team found about 174 particle interactions that are consistent… Read more »
  • CERN’s Large Hadron Collider Creates Matter From LightCERN’s Large Hadron Collider Creates Matter From Light
    The ATLAS detector at CERN’s Large Hadron Collider. (Credit: CERN) Note: This article was originally published by Symmetry magazine. Read the original article. The Large Hadron Collider (LHC) plays with Albert Einstein’s famous equation, E = mc², to transform 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. Last year, the ATLAS experiment at CERN’s LHC observed two photons, particles of light, ricocheting off one another and producing two new photons. This year, scientists have taken that research… Read more »

    The South Pole Telescope scans the sky as the southern lights, or aurora australis, form green patterns in this 2018 video clip. The CMB-S4 project will feature new telescopes around this site of current experiments at the South Pole, and also in Chile’s high desert. (Credit: Robert Schwarz/University of Minnesota) 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… Read more »

(Credit: Ana Lyons) Inspired by the nation’s grappling with issues of race and racial discrimination in the wake of George Floyd’s May 25 killing by police during his arrest in Minneapolis, UC Berkeley physics major and Berkeley Lab student assistant Ana Lyons turned to art as a way to contribute to the conversation. Aware of the scientific community’s own self-reflection for its history of racial inequity and discrimination, Lyons found solace and positivity in a poster project honoring the contributions of Black American physicists. The project… Read more »
