From the Observador (Portugal), April 18, 2021: The Muon g-2 experiment confirmed a small discrepancy previously detected between the measured values and those calculated by the most advanced theory we have with the probability that this measure is a statistical error is 1 in 100,000.

An experiment that will contribute vital knowledge about something deceptively simple – a proton’s spin – will soon come online at Fermilab. The experiment may either begin to validate the “potato salad” model of proton spin or force scientists to develop a new model entirely.

From NewScientist, March 8, 2021: The recent experiment results of asymmetry in protons published in Nature calling out the new research used to improve measurement techniques from Fermilab’s SeaQuest detector.

From Reccom Magazine, Feb. 26, 2021: Chuck Brown of the Fermilab SeaQuest research team is quoted in this piece on the sea of quarks inside the proton. The article discusses Fermilab’s contributions to the SeaQuest and NuSea experiments.
