The Muon g − 2 experiment at Fermilab
Published 2019-01-01“…The current ~ 3.5σ discrepancy between the experimental measurement and theoretical prediction of the muon magnetic anomaly, aµ, stands as a potential indication of the existence of new physics. The Muon g − 2 experiment at Fermilab is set to measure aµ with a four-fold improvement in the uncertainty with respect to previous experiment, with an aim to determine whether the g − 2 discrepancy is well established. …”

The history of the muon (g-2) experiments
Published 2019-02-01“…I discuss the history of the muon $(g-2)$ measurements, beginning with the Columbia-Nevis measurement that observed parity violation in muon decay, and also measured the muon $g$-factor for the first time, finding $g_\mu=2$. …”

Muon g − 2: A review
Published 2022-02-01“…It also provides an overview on resulting constraints of associated physics beyond the SM (BSM), future muon g−2 experiments and on the progress of experiments that are closely connected to the physics of the muon g−2, such as measurements that could provide complementary information about BSM physics in the muon sector.…”

The muon g − 2 and degenerate supersymmetry
Published 2016-01-01“…We find that, with superpartners ~ 800 – 1000 GeV, it is still possible to escape the present limits from the first run of LHC and flavor physics and can account for muon g − 2 within 2σ.…”

Muon g − 2 in Higgs-anomaly mediation
Published 2020-06-01“…In this paper, we show that, although the muon g − 2 explanation in originally proposed Higgs-anomaly mediation with M inp ∼ 1016 GeV is slightly disfavored by the latest LHC data, the muon g − 2 can still be explained at 1σ level when Higgs mediation becomes important at the intermediate scale, M inp ∼ 1012 GeV. …”
