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.
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.
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.
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.
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.
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.
An international group of more than 260 scientists has produced one of the most stringent tests to date for the existence of sterile neutrinos, which are theorized particles related to the three known types, or “flavors,” of neutrinos but that are not directly detectable.
Natalie Roe, who joined Lawrence Berkeley National Laboratory (Berkeley Lab) as a postdoctoral fellow in 1989 and has served as Physics Division director since 2012, has been named the Lab’s Associate Laboratory Director (ALD) for the Physical Sciences Area. Her appointment was approved by the University of California today and was effective July 1, 2020. The announcement follows an international search.
