“…Its experimental value is derived from the measurement of the cyclotron frequency ν c = eB 2πme and the anomaly frequency ν a = ν s − ν c (where ν s = (g e /2)ν c is the spin frequency) of a single electron in a constant magnetic field B. In 2022, G. Gabrielse's team improved their 2008 measurement by a factor of 2.2, reaching a relative accuracy of 0.13 ppt on the value of a e [368]. The new value is consistent with the previous one [369].…”

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebly-interacting particles as a paradigm complementary to a New Physics sector at the TeV scale and beyond. FIPs 2020 has been the first workshop fully dedicated to the physics of feebly-interacting particles and was held virtually from 31 August to 4 September 2020. The workshop has gathered together experts from collider, beam dump, fixed target experiments, as well as from astrophysics, axions/ALPs searches, current/future neutrino experiments, and dark matter direct detection communities to discuss progress in experimental searches and underlying theory models for FIPs physics, and to enhance the cross-fertilisation across different fields. FIPs 2020 has been complemented by the topical workshop “Physics Beyond Colliders meets theory”, held at CERN from 7 June to 9 June 2020. This document presents the summary of the talks presented at the workshops and the outcome of the subsequent discussions held immediately after. It aims to provide a clear picture of this blooming field and proposes a few recommendations for the next round of experimental results.

“…The electron is a key player in this quest: its magnetic moment is both the most precisely measured elementary-particle property and the most accurately verified standard model prediction to date. New measurements by Gerald Gabrielse's group at Northwestern University in Illinois [1] have determined the value of the electron's magnetic moment 2.2 times more accurately than the previous best estimate, which was obtained in 2008 [2]. The result paves the way for much larger accuracy improvements in the next few years, offering tantalizing prospects for using these measurements to search for physics beyond the standard model.…”
