Peter Higgs, a giant of particle physics, dies at 94

    The science world is mourning the loss of British theoretical physicist, Peter Higgs who passed away at the age of 94. He was the namesake of the boson that was discovered in 2012. The Higgs boson was a crucial to the theoretical edifice that physicists built known as the standard model of particles and fields.

    ProtoDUNE’s argon filling underway

      CERN’s ProtoDUNE has entered a pivotal stage: the filling of one of its two particle detectors with liquid argon. The liquid argon will provide a clean environment for precise measurements in neutrino interactions and allow scientists to detect and study neutrino interactions.

      ‘This is our Muon Shot’

      In December, the Particle Physics Project Prioritization Panel released its recommendations for the future of the field. Among the top priorities was research and development toward future accelerator technology, with a specific mention of the concept of building a muon collider in the U.S.

      ATLAS provides first measurement of the W-boson width at the LHC

        The ATLAS collaboration measured the W-boson width at the LHC for the first time. The W-boson width had previously been measured at CERN’s LEP collider and Fermilab’s Tevatron collider. This is the most precise measurement to date made by a single experiment, and—while a bit larger—it is consistent with the Standard-Model prediction to within 2.5 standard deviations.

        Researchers say neutron stars are key to understanding elusive dark matter

          Neutron stars are like huge natural dark matter detectors and might hold a key to helping us understand elusive dark matter. By observing a cold neutron star, physicists from the ARC Centre of Excellence for Dark Matter Particle Physics, might have vital information about the interactions between dark and regular matter, shedding light on the nature of this elusive substance. Dr. Sandra Robles of Fermilab is part of the collaboration on this research.

          First results from BREAD experiment demonstrate a new approach to searching for dark matter

            A collaboration scientists working on the Broadband Reflector Experiment for Axion Detection recently released their first results in the search for dark matter. Although they did not find dark matter, they narrowed the constraints for where it might be and demonstrated a unique approach that may speed up the search for the mysterious substance, at relatively little space and cost.
