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.
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.
Giant-scale physics experiments are increasingly reliant on big data and complex algorithms fed into powerful computers, and managing this multiplying mass of data presents its own unique challenges. To better prepare for this data deluge posed by next-generation upgrades and new experiments, physicists are turning to the fledgling field of quantum computing.
A groundbreaking ceremony today celebrates the start of civil engineering work for a major upgrade to the Large Hadron Collider at CERN in Geneva, Switzerland. When complete, the High-Luminosity LHC will produce five to seven times more proton-proton collisions than the currently operating LHC, powering new discoveries about our universe.
