Electron and muon magnetic moments search for New Physics ⚡ экспресс
Original: "Lepton $$g-2$$ non-universality of hadronic contributions and a sub-GeV window to New Physics"
Combining data on the magnetic properties of two particles filters out noise and tests theory more precisely.

The secret of the magnet: scientists found a way to combine the magnetic properties of the electron and muon to remove interference and peek into the world of unknown particles. When measurement precision improves, this trick will open a window to New Physics. Magic in simple arithmetic!
🎯 The muon is about 207 times heavier than the electron but lives only 2.2 microseconds—a true mayfly of the microworld.
a_{\mu-e} \equiv a_\mu - (m_\mu/m_e)^2 a_e
Subtracting the anomalous magnetic moments of the muon and electron with a weight depending on the masses cancels out common interfering contributions.
