‘Ghostly’ neutrinos provide new path to study protons

    From Science Daily, Feb. 1, 2023: Yesterday, Nature posted new research which used a beam of neutrinos for the first time to investigate the structure of protons. With Fermilab’s MINERvA detector, scientists were able to precisely measure the proton’s size and structure using neutrinos with data gathered from thousands of neutrino-hydrogen scattering events.

    3 new studies indicate a conflict at the heart of cosmology

      From Big Think, Jan. 31, 2023: Fermilab researchers are part of a group who studied analysis from the South Pole Telescope and the Dark Energy Survey in a series of three scientific papers describing the expansion history of the Universe is tells a confusing tale. The predictions and measurements disagree slightly, it could be a hint that our theories about the Universe need to be revised.

      Cosmological parameters improved by combining data

        From Physics, Jan. 31, 2023: Fermilab scientists are part of a group of researchers using cross-correlation measurements combining data from the Dark Energy Survey and the South Pole Telescope to determine cosmological parameters with greater precision. The analysis involved more than 150 researchers with results published as a set of three articles in Physical Review D.

        Study demonstrates a new method to search for meV dark photons

          From Phys.org, Jan. 25, 2023: Researchers at Fermilab, Northwestern University and Stanford University recently demonstrated an entirely new method for searching for meV dark matter. The group is testing a hypothesis that when the rest energy of a dark photon matches the energy splitting of the two lowest cyclotron levels, the first state of the electron cyclotron will be excited.

          New detectors solve age-old problems

            From Laser Focus World, Jan. 12, 2023: What does the future of detectors look like and what problems will they solve? Advances in novel detectors are working on some of the most elusive mysteries in science—from quantum teleportation to neutrinos and dark matter. The long-baseline neutrino detectors of DUNE are part of this line up of international detectors.
