CMS precisely measures the mass of the Higgs boson

    From CERN, Oct. 15, 2019: A new result by the CMS Collaboration narrows down the mass of the Higgs boson to a precision of 0.1%. After reporting the observation of the Higgs boson at the CERN LHC in 2012, scientists the ATLAS and CMS collaborations have been busy understanding exactly its place within the standard model of particle physics. Any straying from expectations could be an indication of new physics.

    Does the world need a more powerful supercollider?

      From Inside Science, Oct. 11, 2019: Fermilab Director Nigel Lockyer is quoted in this article about the discussion surrounding the world’s next big atom smasher. Europe and China both plan to build one, but scientists are debating if it’s worth it.

      Astronomers use giant galaxy cluster as X-ray magnifying lens

        From UChicago News, Oct. 15, 2019: Astronomers at the University of Chicago, MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation. Fermilab and University of Chicago scientist Brad Benson is a co-author of the study.

        Red Arrows dart across Mt. Rushmore

          From Black Hills Pioneer, Oct. 10, 2019: Representatives from the British Consulate, Fermilab and Sanford Underground Research Facility were on hand for a dinner in Rapid City, South Dakota, in honor of the Red Arrows and the ongoing scientific and technological relations between the UK and the U.S. In 2017, the UK committed $88 million to the Long Baseline Neutrino Facility and the Deep Underground Neutrino Experiment. Fermilab Director Nigel Lockyer notes that the first science and technology agreement between the United States and the United Kingdom was driven by neutrino physics.

          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.
