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.
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.
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.
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.
A new study, led by a team of researchers including Berkeley Lab’s Josh McFayden, dives into a decades-old discrepancy in measurements relating to a Standard Model of particle physics pillar known as “lepton flavor universality,” and provides strong evidence to resolve it.
Even an underground experiment 4,600 feet below a mountain in Central Italy, and a telescope instrument more than a mile high atop an Arizona mountaintop could not escape the impacts of the COVID-19 pandemic. In these videos, a Berkeley Lab scientist and two Berkeley Lab-affiliated researchers share their experiences of working in international collaborations during the COVID-19 pandemic.
While COVID-19 risks had led to a temporary halt in fabrication work on high-power superconducting magnets built by a collaboration of three U.S. Department of Energy national labs for an upgrade of the world’s largest particle collider at CERN in Europe, researchers at Berkeley Lab are still carrying out some project tasks.
Marjorie Shapiro, an experimental particle physicist and faculty senior scientist at Berkeley Lab, has been accustomed to working remotely and observing extreme social distancing from some colleagues for years, given that the scientific experiment she supports is 5,800 miles away.
Two Berkeley Lab scientists and a visiting scientist are among the newest elected members of the American Academy of Arts and Sciences – a 240-year-old honorary society that recognizes accomplished scholars, scientists and artists in academia, the humanities, arts, business, and government.
