A review of the experimental and theoretical determinations of the anomalous magnetic moment of the muon is given. The anomaly is defined by a=(g-2)/2, where the Land\'e g-factor is the proportionality constant that relates the spin to the magnetic moment. For the muon, as well as for the electron and tauon, the anomaly a differs slightly from zero (of order 10^{-3}) because of radiative corrections. In the Standard Model, contributions to the anomaly come from virtual `loops' containing… Expand
Understanding the MiniBooNE and the muon and electron g − 2 anomalies with a light Z′ and a second Higgs doublet
Two of the most widely studied extensions of the Standard Model (SM) are a) the addition of a new U(1) symmetry to its existing gauge groups, and b) the expansion of its scalar sector to incorporateExpand
Anomalous g-Factors for Charged Leptons in a Fractional Coarse-Grained Approach
In this work, we investigate aspects of the electron, muon and tau gyromagnetic ratios (g-factor) in a fractional coarse-grained scenario, by adopting a Modified Riemann-Liouville (MRL) fractionalExpand
The muon g ― 2
Abstract The muon anomalous magnetic moment is one of the most precisely measured quantities in particle physics. In a recent experiment at Brookhaven it has been measured with a remarkable 14-foldExpand
Muon g−2 in a U(1) -symmetric two-Higgs-doublet model
We show in this paper that, in a $U(1)$-symmetric two-Higgs-doublet model (2HDM), the two additional neutral Higgs bosons would become nearly degenerate in the large $\tan\beta$ regime, under theExpand
Search for the Electric Dipole Moment and anomalous magnetic moment of the tau lepton at tau factories
Abstract 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. It is generallyExpand
Pion light-by-light contributions to the muon g − 2
A bstractThis paper contains some new results on the hadronic light-by-light contribution (HLbL) to the muon g − 2. The first part argues that we can expect large effects from disconnected diagramsExpand
Gauged U(1)Lμ−Lτ model in light of muon g − 2 anomaly, neutrino mass and dark matter phenomenology
Gauged U(1)Lμ−Lτ model has been advocated for a long time in light of muon g−2 anomaly, which is a more than 3σ discrepancy between the experimental measurement and the standard model prediction. WeExpand
Pseudoscalar pole light-by-light contributions to the muon (g − 2) in resonance chiral theory
A bstractWe have studied the P → γ⋆γ⋆ transition form-factors (P = π0, η, η′) within a chiral invariant framework that allows us to relate the three form-factors and evaluate the correspondingExpand
Anomaly of Zbb̄ coupling revisited in MSSM and NMSSM
The Zb coupling determined from the Z-pole measurements at LEP/SLD shows an about 3σ deviation from the SM prediction, which would signal the presence of new physics in association with the ZbExpand
Gravitino decay in high scale supersymmetry with R-parity violation
We consider the effects of R-parity violation due to the inclusion of a bilinear $\mu^\prime L H_u$ superpotential term in high scale supersymmetric models with an EeV scale gravitino as dark matter.Expand
