The muon electric dipole moment (EDM) is a sensitive probe of charge-parity (CP) violation and physics beyond the Standard Model. In the Fermilab Muon g−2 experiment, an EDM introduces an additional spin-precession component that produces a vertical oscillation in the decay-positron distribution that can be measured by the calorimeters. For a muon EDM smaller than the current limit set by the...

The Reactor Antineutrino Anomaly (RAA)—a long-standing discrepancy between the measured and predicted antineutrino flux—has been a cornerstone in the search for light sterile neutrinos.

However, new experimental results, most notably from the BEST gallium...
