Muon anomalous magnetic dipole moment in supersymmetric theories [PDF]
Physical Review D, 2001 We study the muon anomalous magnetic dipole moment in supersymmetric theories. The impact of the recent Brookhaven E821 experimental measurement on both model-independent and model-dependent supersymmetric parameter spaces is discussed in detail. We find

Muon anomalous magnetic dipole moment in a low scale type I see-saw model
Nuclear Physics B, 2023 Recent experimental results on muon anomalous magnetic dipole moment have shown a 4.2σ tension with the SM prediction, which has blown a fresh wind into the elementary particle physics community.

Electron and muon anomalous magnetic dipole moment in a 3–3–1 model [PDF]
Journal of High Energy Physics, 2017 We calculate, in the context of a 3–3–1 model with heavy charged leptons, constraints on some parameters of the extra particles in the model by imposing that their contributions to both the electron and muon (g − 2) factors are in agreement with ...

Anomalous magnetic and weak magnetic dipole moments of the $$\tau $$ τ lepton in the simplest little Higgs model [PDF]
European Physical Journal C: Particles and Fields, 2017 We obtain analytical expressions, both in terms of parametric integrals and Passarino–Veltman scalar functions, for the one-loop contributions to the anomalous weak magnetic dipole moment (AWMDM) of a charged lepton in the framework of the simplest ...

Search for the Electric Dipole Moment and anomalous magnetic moment of the tau lepton at tau factories [PDF]
Journal of High Energy Physics, 2019 Precise measurement of the Electric Dipole Moment (EDM) and anomalous magnetic moment (g-2) of particles are important tests of Beyond Standard Model (BSM) physics.

Tests of CPT and Lorentz symmetry from muon anomalous magnetic dipole moment [PDF]
Physical Review D, 2014 We derive the relativistic factor for splitting of the $g$-factors of a fermion and its anti-fermion partner, which is important for placing constraints on dimension-5, $CPT$-odd and Lorentz-invariance-violating interactions from experiments performed in

European Physical Journal C: Particles and Fields, 2022 The new results on the muon anomalous magnetic moment (AMM) published by Fermilab in 2021 did not lead to a reduction of its long-pending deviation from the Standard Model (SM) value by more than 4 $$\sigma $$ σ .

Muon anomalous magnetic dipole moment in the μ νSSM *
Chinese Physics C, 2022 Abstract Recently, the Muon g-2 experiment at Fermilab measured the muon anomalous magnetic dipole moment (MDM), , and reported that the new experimental average increases the difference between the experiment and the standard model (SM) prediction to 4.2σ. In this work,

Impact of Anomalous Active Regions on the Large-scale Magnetic Field of the Sun
The Astrophysical Journal, 2023 One of the major sources of perturbation in the solar cycle amplitude is believed to be the emergence of anomalous active regions that do not obey Hale’s polarity law and Joy’s law of tilt angles.

Journal of High Energy Physics, 2021 The difference between the updated experimental result on the muon anomalous magnetic dipole moment and the corresponding theoretical prediction of the standard model on that is about 4.2 standard deviations. In this work, we calculate the muon anomalous
