Sterile neutrinos could explain dark matter – if we can find them

    From New Scientist (UK), November 13, 2021: There are good reasons to think that neutrinos have a shy cousin that could explain dark matter, but searches have so far come up empty, writes Chanda Prescod-Weinstein theoretical physicist specializing in early universe cosmology and a monthly columnist at New Scientist.

    Experiment finds no sign of sterile neutrinos

      From Universe Today, November 5, 2021: Neutrinos might make up a small portion of dark matter, but most dark matter must be something else. Because neutrinos are so close to satisfying the properties of dark matter, some scientists have argued dark matter might be a yet undiscovered variety known as sterile neutrinos.What did Fermilab’s newest experiment MicroBooNE see?

      Still no trace of the sterile neutrino

        From Le Scienze (France), November 4, 2021: The preliminary analysis of three years of data from the MicroBooNE experiment show no signs of the existence of a fourth type of neutrino. The standard model of particle physics remains confirmed but it has not excluded clues to exotic physical phenomena may emerge.

        Can sterile neutrinos exist?

          From Scientific American, November 4, 2021: Physicists have wondered if neutrino particles come in a mysterious fourth variety. Now new experimental findings complicate the question.

          LBNF DUNE excavation achieves a gem of a milestone

            From Rapid City Journal-Our Northern Hills, November 4, 2021: Excavation crews at the underground site of DUNE reached an important milestone. They completed the careful excavation of the ventilation shaft with just one drill bit during the entire four-and-a-half-month process. Crews also uncovered a 1-1/2 foot thick chunk of quartz crystal during the process that miraculously was not damaged by the reamer head, nor by the 300-foot fall it sustained, marking it a gem of the milestone.

            Can sterile neutrinos exist?

Physicists have wondered if neutrino particles come in a mysterious fourth variety. The MicroBooNE experiment findings announced last week by Fermilab heightened the mystery of why too many particles showed up in a detector during an experiment on the 1990s.

              A minute with Cristián Peña, associate scientist at the Fermilab Quantum Institute

              Whether he is on the side of a mountain or working at the Fermilab Quantum Institute, Cristián Peña likes to explore the unknown and tackle new challenges. Although he spends most of his time working on quantum communication systems for FQI, Peña dedicates time to work on the CMS experiment. His work between the two experiments, while different in practice, are conceptually similar.
