neutrino

This is a visual display of an ArgoNeuT event showing a long trail left behind by a high energy particle traveling through the liquid argon accompanied by small blips caused by low energy particles.

For the first time, scientists have demonstrated that low-energy neutrinos can be thoroughly identified with a liquid-argon particle detector. The results, obtained with the ArgoNeuT experiment, are promising for experiments that use liquid argon to catch neutrinos, including the upcoming Deep Underground Neutrino Experiment.

Agencies in the United States and France have signed statements expressing interest to work together on the development and production of technical components for PIP-II, a major particle accelerator project with substantial international contributions. In addition, the French agencies also plan to collaborate on DUNE, an international flagship science project that will unlock the mysteries of neutrinos.

The upcoming Short-Baseline Near Detector at Fermilab continues scientists’ search for evidence of a hypothetical particle, the sterile neutrino. Collaborators around the world are participating in the detector’s construction. Its first critical components recently arrived from partner institutions. When complete, SBND will be the third and final detector in Fermilab’s Short-Baseline Neutrino Program.

From Québec Science, Dec. 3, 2018: La mise en service d’immenses détecteurs au Fermilab, aux États-Unis, pourrait prochainement faire la lumière sur des particules aussi bizarres que prometteuses: les neutrinos.

From This Week in Science, Nov. 28, 2018: Fermilab scientist Alex Himmel talks about neutrinos, DUNE and the excitement of particle physics. Segment starts at 5:01.

From New Scientist, Nov. 21, 2018: Elusive though it is, the sterile neutrino would be a real boon. It could make sense of experimental anomalies stretching back decades, and give us the first confirmed glimpse of physics beyond what we know. Subscription required.
