Serving society: Keenan Newton volunteers as Illinois incident manager

Typically, Fermilab employee Keenan Newton spends his days managing Fermilab’s main content management platforms and his nights and weekends as a volunteer firefighter. Now he’s arranged his schedule to serve the Illinois Emergency Management Agency, volunteering his personal time to help people during the current pandemic and responding to hazardous situations while based at the State Emergency Operations Center in Springfield.

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.

    Biggest cosmic mystery ‘step closer’ to solution

      From BBC News, April 16, 2020: Stars, galaxies, planets, pretty much everything that makes up our everyday lives owes its existence to a cosmic quirk. The nature of this quirk, which allowed matter to dominate the universe at the expense of antimatter, remains a mystery. Now, results from the T2K experiment in Japan has given strong hints that the CP violation effect could be large for neutrinos. The international Deep Underground Neutrino Experiment, hosted by Fermilab, might detect the effect faster than expected.

      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.

              Why the Big Bang produced something rather than nothing

                From The New York Times, April 15, 2020: An international team of 500 physicists from 12 countries, known as the T2K collaboration, reported that they had measured a slight but telling difference between neutrinos and their opposites, antineutrinos. Fermilab Deputy Director Joe Lykken comments on the result and how the international Deep Underground Neutrino Experiment, hosted by Fermilab, may be able to make a definitive discovery of CP violation.
