The W boson’s midlife crisis

    Forty years after its discovery, the W boson continues to intrigue scientists. Chris Hays describes recent progress in understanding a surprisingly high measurement of its mass using data from the former CDF experiment at Fermilab.

    In preparation for DUNE, scientists examine modern nuclear theory for neutrino oscillation physics

      Current understandings of neutrino-nucleon interactions rely on data from experiments in the 1970s and ’80s. However, by using lattice quantum chromodynamics to predict stronger neutrino-nucleon interactions, scientists can determine oscillation properties of the elusive neutrinos in Fermilab’s DUNE experiment and other neutrino oscillation experiments.

      A fleeting subatomic particle may be exposing flaws in a major physics theory

        From Popular Science, August 17, 2023: Breaking the Standard Model would be one of the biggest moments in particle physics history. The Muon g-2 collaboration reported that the muon doesn’t always look like physicists expect it to look, but the collaboration isn’t done. Once they analyze all the remaining data, physicists believe they can make their g minus 2 estimate twice as precise again.

        Fermilab awards contract to build first underground cryogenic system

          Plans are moving ahead for the liquid nitrogen refrigeration system which will use liquid nitrogen to cool the 17,500 tons of liquid argon that will fill the neutrino detectors at the Long Baseline Neutrino Facility in the Sanford Lab. The system is expected to be built by 2026, and operational underground by the end of 2026 to support the installation of some detector elements, and the operations of the full facility starting in early 2028.
