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.
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.
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.
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.
A new set of calibration techniques employed by LUX scientists has again dramatically improved the detector’s sensitivity.
On November 8, Silicon Valley’s ritzy, glitzy 2016 Breakthrough Prizes honored five neutrino experiments with $3 million prizes in Fundamental Physics. Three of the five, SNO, KamLAND, and Daya Bay, were made possible by Berkeley Lab scientists and engineers.
Berkeley Lab scientists and engineers played important roles in the design and construction of SNO – the Sudbury Neutrino Observatory – as well as subsequent data analysis that contributed to the 2015 Nobel Prize in Physics awarded to Canada’s Arthur McDonald.
In the Daya Bay region of China a research project is underway to study ghostlike, elusive particles called neutrinos. Today, the international Daya Bay Collaboration announces new findings on the measurements of neutrinos, paving the way forward for further neutrino research, and confirming that the Daya Bay neutrino experiment, significant as the first equal partnership between the U.S. and China in a major physics project, continues to be one to watch.
Evidence of a fourth ultra-high energy neutrino—the highest-energy neutrino yet—has been detected by the South Pole-based IceCube experiment.
The town of Lead South Dakota has a hidden gem: an enormous, underground mine that’s been retrofitted to accommodate large-scale particle physics experiments. These slideshows and videos give a sense of what it’s like to descend 4,850 feet below the surface and work on projects that could shine light on fundamental truths about the universe.
