From The Conversation, Aug. 10, 2023: The new results of the Muon g-2 experiment are summarized by a group of Postdocs from the University of Liverpool. The latest results examined four times as many muons as the 2021 result, cutting the total uncertainty by a factor of two. This makes the measurement the most precise determination of the muon’s wobble ever made on Muon g-2.
Scientists working on Fermilab’s Muon g-2 experiment released the world’s most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown between theory and experiment that may uncover new particles or forces.
A large number of scientists are working on improving the Standard Model prediction of the value of muon g-2 using new data and new lattice calculations. By measuring and calculating this number to ultra-high precision, scientists can test whether the Standard Model is complete.
A theory of everything was all the rage in the 1980s. So where did it go?
The ATLAS and CMS experiments have observed a process 4,000 times rarer than the production of Higgs bosons.
The Higgs boson is the only fundamental particle known to be scalar, meaning it has no quantum spin. This fact answers questions about our universe, but it also raises new ones.
From Big Think, Feb. 15, 2023: The Standard Model of Physics has been challenged by the Muon g-2 and W-boson measurements. Don Lincoln discusses a recent paper in the journal Nature Communications that attempted to resolve two significant discrepancies in particle physics.
For decades, scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed.
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.
From Live Science, Dec. 29, 2022: This past year proved successful for particle physics research. Read more about the eight projects identified by Live Science as the biggest and best physics stories of 2022 and how Fermilab was a part of two of them.
