Will it ''...knock, knock, knocking on SUSY's door...''?! So far, today, there is a 4.2-sigma tension for the SM prediction versus run-1. Interesting...to promising!!!

Muon g-2 (pronounced gee minus two) uses Fermilab's powerful accelerators to explore the interactions of short-lived particles known as muons with a strong magnetic field in "empty" space. Scientists know that even in a vacuum, space is never empty. Instead, it is filled with an invisible sea of virtual particles that in accordance with the laws of quantum physics pop in and out of existence for incredibly short moments of time. Scientists can test the presence and nature of these virtual particles with particle beams travelling in a magnetic field.

The Muon g-2 experimenters examine the precession of muons that are subjected to a magnetic field. The main goal is to test the Standard Model's predictions of this value by measuring the precession rate experimentally to a precision of 0.14 parts per million. If there is any inconsistency, it could indicate the Standard Model is incomplete and in need of revision.
