Run top quark run

    From CERN, Oct. 7, 2019: The CMS collaboration has measured for the first time the variation, or “running,” of the top quark mass. The theory of quantum chromodynamics predicts this energy-scale variation for the masses of all quarks and for the strong force acting between them. Observing the running masses of quarks can therefore provide a way of testing quantum chromodynamics and the Standard Model.

    DUNE scientists see particle tracks with dual-phase technology

    Advances in subatomic physics heavily depend on ingenuity and technology. And when it comes to discovering the nature of some of the most elusive particles in the universe, neutrinos, scientists need the best and most sensitive detector technology possible. Scientists working at CERN have started tests of a new neutrino detector prototype, using a very promising technology called “dual phase.”

    Portal to progress: Science project revives old Homestake tramway tunnel

      From Rapid City Journal, Oct. 9, 2019: For the past 17 years, shovels, safety goggles, tramway cars and other remains of the defunct Homestake gold mine lingered in a closed-off tunnel under the city of Lead, South Dakota. Now the tunnel is alive with activity again, thanks to preparations for the Long-Baseline Neutrino Facility and the international Deep Underground Neutrino Experiment, hosted by Fermilab.

      Une nouvelle technologie innovante pour détecter les neutrinos testée à grande échelle au CERN

        From CNRS, Oct. 10, 2019: Les scientifiques de la collaboration ProtoDUNE au CERN ont commencé à tester un tout nouveau prototype de détecteur de neutrinos, en utilisant une technologie très prometteuse, appelée “double phase.” Si les premiers résultats obtenus se confirment, cette nouvelle technologie sera utilisée à une plus grande échelle pour l’expérience internationale DUNE aux États-Unis. Les scientifiques français du CNRS et du CEA jouent un rôle de premier plan dans le développement et la mise en route de ce détecteur innovant.
