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

Particle detectors recorded neutrinos from supernova SN1987A hours before telescopes saw the first light. Thirty years later, scientists around the world are eager to detect neutrinos from another one. The international Fermilab-hosted Deep Underground Neutrino Experiment will be looking for them. These neutrinos can tell us more about supernovae themselves and may hint at new physics that could upend the Standard Model of particle physics.

Muon g-2 has begun its second run to search for hidden particles and forces. Muon g-2 collaborators have performed upgrades to improve the experiment’s precision and increase the amount of data it generates. As the experiment starts up again, scientists expect to make the world’s most precise measurement of the muon’s anomalous magnetic moment, which could tell us whether additional, undiscovered particles exist in the universe.

Fermilab’s Inclusivity Journal Club seeks answers to difficult social questions in science. A typical meeting includes physicists and postdoctoral researchers as well as non-science staff; students are also welcome to attend. Members read and discuss reports and peer-reviewed papers that address issues such as sexual harassment, implicit bias and best practices for expanding inclusivity.

Lab Libs

‘Tis the season for friends, family and funny physics fill-ins. Here at Symmetry, we’ve taken a page from Mad Libs, those short stories designed to trick you into learning parts of speech, and created some science-themed Lab Libs (to trick you into learning science). Simply fill in the blanks to create original science stories.

The upcoming Short-Baseline Near Detector at Fermilab continues scientists’ search for evidence of a hypothetical particle, the sterile neutrino. Collaborators around the world are participating in the detector’s construction. Its first critical components recently arrived from partner institutions. When complete, SBND will be the third and final detector in Fermilab’s Short-Baseline Neutrino Program.

Gravitational lenses

Predicted by Einstein and discovered in 1979, gravitational lensing helps astrophysicists understand the evolving shape of the universe.
