beyond the Standard Model

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.
