Particle Physicists Lay Out Future Goals at ‘Snowmass’ Meeting
With a picturesque backdrop of Mt. Rainier, particle physicists from across the United States gathered in Seattle (with more tuning in virtually) to assess the most important science opportunities in their field over the next decade. The Particle Physics Community Planning Exercise was held July 17-26, 2022, at the University of Washington.
Direct Neutrino-Mass Measurement Achieves New, Sub-Electronvolt Sensitivity
The international KArlsruhe TRItium Neutrino (KATRIN) experiment in Germany recently reported a new upper limit on the mass of the neutrino. This limit—0.8 electronvolts (eV)—is the lowerst scientists have achieved. As the results are confirmed and refined, they will help scientists better understand the neutrino and its role in the evolution of the universe.
Brookhaven Chemist Minfang Yeh Wins 2021 DPF Instrumentation Award
UPTON, NY—Minfang Yeh, a senior scientist at the U.S. Department of Energy’s Brookhaven National Laboratory, has won the American Physical Society’s 2021 Division of Particles and Fields (DPF) Instrumentation Award. The award honors Yeh’s pioneering work in the development and production of high-performance water-based liquid scintillators for particle physics experiments, including metal loaded scintillators for rare process experiments.
Scientists Spot Rare Neutrino Signal for Big Physics Finding
Scientists at Brookhaven National Laboratory developed a software toolkit that reconstructs and isolates neutrino data in 3D. This software directly enabled the long-awaited findings from the MicroBooNE experiment released today by Fermilab in four complementary analyses. The Wire-Cell team at Brookhaven Lab led one of the four analyses—the most sensitive analysis of the electron-neutrino interaction. Some components of the Wire-Cell toolkit were also used in the other three analyses.
Gamma rays and neutrinos from mellow supermassive black holes
The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles’ origins remain unexplained.
James Kneller: Then and Now / 2011 Early Career Award Winner
At North Carolina State University, associate professor James Kneller studies neutrinos emitted from exploding stars.
Basic to Breakthrough: How Exploring the Building Blocks of the Universe Sets the Foundation for Innovation
Particle physics peers into the mysteries of our cosmos while opening the door to future technologies. Research into the Higgs boson, dark energy, and quantum physics reveals insights into the universe and enables innovation in other fields.
Physicists Achieve Significant Improvement in Spotting Accelerator-produced Neutrinos in a Cosmic Haystack
Scientists demonstrate how ground-breaking image reconstruction and analysis algorithms filter out cosmic ray tracks in the MicroBooNE neutrino detector to pinpoint elusive neutrino interactions with unprecedented clarity.

Patrick Huber: Then and Now / 2010 Early Career Award Winner
Professor Patrick Huber is the director of Virginia Tech’s Center for Neutrino Physics. His research develops and advances theoretical tools to analyze data from neutrino experiments, the results of which will improve our understanding of neutrinos’ properties and their role in the cosmos.
Righting a wrong, nuclear physicists improve precision of neutrino studies
Led by the Department of Energy’s Oak Ridge National Laboratory, a new study clears up a discrepancy regarding the biggest contributor of unwanted background signals in specialized detectors of neutrinos.
Scientists Say Farewell to Daya Bay Site, Proceed with Final Data Analysis
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.
90 Years of Neutrino Science
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.
Researchers validate theory that neutrinos shape the universe
The effect that nearly massless, subatomic particles called neutrinos have on the formation of galaxies has long been a cosmological mystery — one that physicists have sought to measure since discovering the particles in 1956.But an international research team has created cosmological simulations that accurately depict the role of neutrinos in the evolution of the universe in a study recently published in The Astrophysical Journal.
Q&A: How machine learning helps scientists hunt for particles, wrangle floppy proteins and speed discovery

Researchers home in on extremely rare nuclear process
A hypothetical nuclear process known as neutrinoless double beta decay ought to be among the least likely events in the universe. Now the international EXO-200 collaboration, which includes researchers from the Department of Energy’s SLAC National Accelerator Laboratory, has determined just how unlikely it is: In a given volume of a certain xenon isotope, it would take more than 35 trillion trillion years for half of its nuclei to decay through this process – an eternity compared to the age of the universe, which is “only” 13 billion years old.
