beyond the Standard Model

From Scientific American, Dec. 16, 2020: Researchers have made the most precise measurement of one of the fundamental constants, called the fine-structure constant. Now all eyes are on Fermilab, where the first results of the Muon g-2 experiment are expected to provide the most precise experimental measurement of the muon’s magnetic moment. Alex Keshavarzi, scientist on the Muon g-2 experiment, weighs in on the significance of the measurement.

Fermilab scientists have proposed a new experiment, FerMINI, to look for millicharged particles in a specific mass range. These hypothetical particles have charges significantly smaller than that of quarks. The discovery of millicharged particles would upend our understanding of nature’s fundamental constituents.

From Sanford Underground Research Facility, May 26, 2020: Unwilling to ignore flaws in the Standard Model, physicists are looking for a new, more perfect model of the subatomic universe. And many are hoping that the international Deep Underground Neutrino Experiment, hosted by Fermilab, can put their theories to the test.

In their quest to discover physics beyond the Standard Model, physicists weigh the pros and cons of different search strategies.
