International Physicists Join Forces in Hunt for Sterile Neutrinos

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.

Scientists Successfully Demonstrate a New Experiment in the Search for Theorized ‘Neutrinoless’ Process

Berkeley Lab-affiliated researchers played a leading role in analyzing data for a demonstration experiment in France that has achieved record precision for a specialized detector material.

Daya Bay Reactor Experiment Continues to Generate Data

Largely unaffected by the pandemic, the Daya Bay reactor neutrino experiment in Shenzen, China, has continued to pump data to remote supercomputers for analyses.

CUORE Underground Experiment in Italy Carries on Despite Pandemic

As the COVID-19 outbreak took hold in Italy, researchers working on a nuclear physics experiment called CUORE at an underground laboratory in central Italy scrambled to keep the ultrasensitive experiment running and launch new tools and rules for remote operations.

KATRIN Cuts the Mass Estimate for the Elusive Neutrino in Half

An international team of scientists that includes Berkeley Lab researchers has announced a breakthrough in its quest to measure the mass of the neutrino, one of the most abundant yet elusive elementary particles in our universe.

First Particle Tracks Seen in ProtoDUNE: the Prototype for an International Neutrino Experiment

The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE). DUNE’s scientific mission is dedicated to unlocking the mysteries of neutrinos, the most abundant (and most mysterious) matter particles in the universe.

Q&A: Berkeley Lab’s Spencer Klein Talks About IceCube Then and Now, and What’s Next

In this Q&A, Berkeley Lab physicist Spencer Klein, who has been a part of the IceCube collaboration since 2004, discusses Berkeley Lab’s historic contributions to IceCube, and IceCube’s contributions to science.

Experiment Provides Deeper Look into the Nature of Neutrinos

The first glimpse of data from the full array of a deeply chilled particle detector operating beneath a mountain in Italy sets the most precise limits yet on where scientists might find a theorized process to help explain why there is more matter than antimatter in the universe.

Most Precise Measurement of Energy Range for Particles Produced by Nuclear Reactors Reveals Surprises

An international team that includes researchers from Berkeley Lab has captured the most precise—and puzzling—energy measurements yet of ghostly particles called reactor antineutrinos produced at a nuclear power complex in China.

New Results from World’s Most Sensitive Dark Matter Detector

A new set of calibration techniques employed by LUX scientists has again dramatically improved the detector’s sensitivity.
