This underground experiment will hunt for supernova shrapnel

    From Futurism, Aug. 19, 2020: When an ambitious new Fermilab-hosted experiment called DUNE begins its work, physicists believe they’ll be able to learn a whole lot more about supernova explosions than ever before. That’s because DUNE is expected to be sensitive to an extremely elusive particle called a neutrino that’s blasted far and wide across the cosmos when a star explodes. According to a new paper shared online on Saturday, physicists expect DUNE to scoop up a never-before-detected kind of neutrino and, in doing so, break down why and how stars die in unprecedented detail.

    Conveyor that stretches over US Hwy 85 near completion

      From Rapid City Journal, Aug. 6, 2020: Crews have begun installing a rock conveyor over U.S. Highway 85 in Lead, South Dakota, for the Long-Baseline Neutrino Facility. The conveyor will bring 800,000 tons of rock from the 4850 level of Sanford Underground Research Facility and deposit them into an open pit mining area that was excavated by the Homestake Gold Mine in the 1980s, making way for the international Deep Underground Neutrino Experiment, hosted by Fermilab.

      ‘Truss’le and bustle

        From Black Hills Pioneer, July 22, 2020: Since late 2019, work has been underway on the Long-Baseline Neutrino Facility conveyor system at the Sanford Underground Research Facility in South Dakota. The system will carry more than 800,000 tons of rock excavated from the site of the international, Fermilab-hosted Deep Underground Neutrino Experiment 4,850-feet below the surface. A major milestone for the project was met on July 20 as the 120-foot section of the truss, which will house the conveyor, was erected above the highway.

        Accelerator experiments are closing in on neutrino CP violation

          From Physics Today, June 1, 2020: Somewhere in the laws of physics, particles must be allowed to behave differently from their antiparticles. If they weren’t, the universe would contain equal amounts of matter and antimatter, all the particles and antiparticles would promptly annihilate one another, and none of us would exist. Fermilab’s NOvA neutrino experiment and the international Deep Underground Neutrino Experiment, hosted by Fermilab, are pinning down CP violation, the property that could explain the imbalance.

          Why the U.S. is betting it all on the most puzzling particle in the universe

            From Gizmodo, May 18, 2020: Neutrino physics is a trek into the unknown, one that the United States physics community has chosen to pursue full-on. A flagship experiment called LBNF/DUNE will lead the search, in pursuit of answers that may take decades or more to find. Fermilab Deputy Director for Research Joe Lykken, DUNE spokesperson Ed Blucher, and DUNE scientists Chang Kee Jung and Elizabeth Worcester talk about how neutrinos will enhance our understanding of the universe.

            Neutrino asymmetry passes critical threshold

              From Quanta Magazine, April 15, 2020: The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing. Fermilab scientist Debbie Harris comments on the T2K experiment’s latest result. Fermilab’s NOvA experiment and the international Deep Underground Neutrino Experiment, hosted by Fermilab, will also help provide a more precise understanding of the asymmetry.

              Weird neutrino behavior could explain longstanding antimatter mystery

                From Space.com, April 15, 2020: A new study from the T2K experiment looked hard for signs of CP symmetry violation in neutrinos and came up with some intriguing results. The international Deep Underground Neutrino Experiment, hosted by Fermilab, will provide complementary techniques and measurements that may provide a more definitive answer in the quest for CP violation.

                Skewed neutrino behavior could help explain matter’s dominion over antimatter

                  From Science, April 15, 2020: Neutrinos behave differently from their antimatter counterparts, antineutrinos, report physicists on the T2K experiment. The result is far from conclusive, but the asymmetry, known as CP violation, could help explain how the newborn universe generated more matter than antimatter. NOvA spokesperson Patricia Vahle of William & Mary comments on the T2K result and NOvA’s measurements of CP violation. When the international Deep Underground Neutrino Experiment, hosted by Fermilab, comes online, it will be able to make more precise measurements of neutrinos’ behavior.

                  Neutrinos may explain why we don’t live in an antimatter universe

                    From New Scientist, April 15, 2020: Differences between matter and antimatter, called CP violation, have been measured in some particles, called quarks, but the level isn’t nearly enough to explain the observed imbalance between matter and antimatter. The T2K collaboration has observed hints that CP violation in neutrinos may be able to make up the difference. DUNE spokesperson Ed Blucher of the University of Chicago comments on the result.

                    Matter-antimatter symmetry violated

                      From Nature, April 15, 2020: In a mirror world, antiparticles should behave in the same way as particles. But it emerges that neutrinos, electrons and their more exotic cousins might not obey this expected pattern. Fermilab scientist Jessica Turner and Durham University scientist Silvia Pascoli provide a commentary on T2K’s recent neutrino result, CP violation, and how other neutrino experiments, including the international Deep Underground Neutrino Experiment, hosted by Fermilab, will make more precise measurements of the mysterious neutrino’s behavior.
