New physics? Ultra-precise measurement in particle physics confounds scientists

    From Big Think, Jan. 10, 2023: While the Standard Model is the best theory available in modern physics to explain subatomic physics, it cannot explain why antimatter isn’t observed in nature or provide an explanation for dark matter and dark energy. Don Lincoln explains how recent measurements of muons and electrons are propelling the idea that there may be undiscovered laws of nature yet to discover.

    Wobbling into the new frontier of physics: VSP Awardee Brynn MacCoy contributes detector systems to Muon g-2 experiment to test Standard Model

      From the Universities Research Association, October 31, 2022: Brynn MacCoy is a physics doctoral candidate at the University of Washington and the Fall 2019 URA Visiting Scholar Program (VSP) Awardee. With an extension of URA assistance, MacCoy returned to Fermilab earlier this year allowing her to install the Minimally Intrusive Scintillating Fiber Detector.

      Rule-breaking particles pop up in experiments around the world

        From Scientific American, October 2022: For several decades after the invention of the Standard Model, several physics measurements suggest that novel particles and forces exist in the universe. This article was originally published and titled, “When Particles Break the Rules” and includes the combined results from the Fermilab g-2 experiment and the previous trial at Brookhaven that add up to a probability of less than 0.01 percent that this anomaly is a statistical fluke.

        Morse and Roberts win W.K.H. Panofsky Prize for Muon g-2 experiment

          From Brookhaven National Laboratory, October 11, 2022: Brookhaven National Lab announced yesterday that two of their scientists who led the “E821 g-2” experiment at BNL from 1990 through 2004 received the APS’s 2023 W.K.H. Panofsky Prize in Experimental Particle Physics. William M. Morse and Bradley Lee Roberts received the honor for their leadership and technical ingenuity in achieving a measurement of the muon anomalous magnetic moment with a precision suitable to probe Standard Model.

          Physicists spotted rare W boson trios at the Large Hadron Collider

            From Science News, August 15, 2022: W bosons are particles that transmit the weak force, which is responsible for certain types of radioactive decay. Last April, Fermilab researchers reported the W boson was more massive than predicted, hinting that something may be amiss with the standard model. Now a team of scientists with ATLAS at the LHC are reporting rare boson triplets which continues to test the standard model for any cracks.
