The supersymmetric contribution to the muon g-2 is studied in light of the finalization of the LEP electroweak precision data. The recent precise measurement of the muon g-2 of E821 experiment is explained well by the relatively light chargino and sleptons. We find that such the MSSM ...
using all of the known forces and particles in the Standard Model, we don’t get the same answer,” explained Renee Fatemi, the University of Kentucky physicist who managed the simulations for the Muon g-2 experiment, in an interview
In the purple region, aμ can be explained and constraints from Higgs decays are fulfilled. The blue region corresponds to the error interval of Δaμ. The orange region corresponds to the limits on h0→γγ. The red (green) dashed line indicates the upper limit on h0→γZ(h0→μμ) ...
The new result for the Run 1 data of the “MUON G-2” experiment confirmed the deviation from the SM prediction found previously. The combination of the experimental results yields a discrepancy with the theory world average for the SM prediction of Δaμ=(25.1±5.9)×10−10, corresponding...
Today's publication by the Muon g-2 Theory Initiative marks the first time the global theoretical physics community has come together to publish a consensus value for the muon's magnetic moment. Now the world awaits the result from Fermilab's current Muon g-2 experiment, whose magnetic storage...
Although i→jγ puts severe bounds on some couplings, it is found that the excesses of P5′ and the muon g2 can still be explained and accommodated to the measurement of Bs→μ+μ in this model. In addition, the leptoquark effects can also explain the LHCb measurement of RK=BR(B+→...

In this experiment positive polarized muons are implanted into a sample that had been placed in a magnetic field. The precession of the muons at γμ/2π = 135.5MHz/T provides a microscopic probe of the distribution of the local magnetic fields (Budnick et al., 1987). In particular, the...
4 Muon magnetic anomaly at Fermilab The muon g-2 experiment will now move from BNL to Fermilab [21]. The new experiment aims for a 5-fold improvement over the BNL result. The ring magnet, the central device, is presently being dismantled at BNL and it will be reinstalled in a new ...
