 Probing the Standard Model to 0.37 ppm with the muon anomalous magnetic moment / Lellouch, Laurent (speaker) (CNRS & Aix-Marseille U.)
For the past fifty years, the Standard Model has been hugely successful in describing subatomic phenomena. However, recent measurements of the anomalous magnetic moment of the muon (a_mu) appear to challenge that statement, as they show a significant discrepancy with the reference Standard Model prediction. [...]

QED Logarithms in the Electroweak Corrections to the Muon Anomalous Magnetic Moment / Degrassi, G. (CERN) ; Giudice, G.F. (CERN)
We employ an effective Lagrangian approach to derive the leading-logarithm two-loop electroweak contributions to the muon anomalous magnetic moment, a_mu. We show that these corrections can be obtained using known results on the anomalous dimensions of composite operators. [...]

The Hadronic Contribution to the Muon Anomalous Magnetic Moment and to the Running Electromagnetic Fine Structure Constant at MZ - Overview and Latest Results / Hoecker, Andreas (CERN)
Quantum loops induce an anomaly, a_mu, in the magnetic moment of the muon that can be accurately measured. Its Standard Model prediction is limited in precision by contributions from hadronic vacuum polarisation of the photon. [...]

Lattice calculations and the muon anomalous magnetic moment / Marinkovic, Marina Krstic (Trinity Coll., Dublin ; CERN)
Anomalous magnetic moment of the muon, $a_{\mu}=(g_{\mu}-2)/2$, is one of the most precisely measured quantities in particle physics and it provides a stringent test of the Standard Model. The planned improvements of the experimental precision at Fermilab and at J-PARC propel further reduction of the theoretical uncertainty of $a_{\mu}$. [...]

Leading hadronic contribution to the muon magnetic moment from lattice QCD. / Lellouch, Laurent (speaker) (CNRS and Aix-Marseille U.)
Twenty years ago in an experiment at Brookhaven National Laboratory, physicists measured the muon's anomalous magnetic moment, $a_\mu=(g_\mu-2)/2$, with a remarkable precision of 0.54 parts per million. Since then, the standard model prediction for $a_\mu$ has exhibited a discrepancy with experiment of over 3 standard deviations, raising the tantalizing possibility of physical particles or forces as yet undiscovered. [...]

Precision muon g-2 results and light Higgs bosons in the 2HDM(II) / Krawczyk, Maria (CERN ; Warsaw U.)
We discuss the implications of the recent evaluations of the SM contribution to a_mu=(g-2)_mu/2 in the light of the latest E821 measurement, which indicate \~ 3 sigma deviation. We derive the 95 % CL interval, delta a_mu, to be used to constrain any additional contribution to a_mu, beyond the SM ones: it has to have a positive sign. [...]

Reevaluation of the hadronic contribution to the muon magnetic anomaly using new $e^{+}e^{-}\to \pi^{+}\pi^{-}$ cross section data from BABAR / Davier, M. (Orsay, LAL) ; Hoecker, A. (CERN) ; Malaescu, B. (Orsay, LAL) ; Yuan, C.Z. (Beijing, Inst. High Energy Phys.) ; Zhang, Z. (Orsay, LAL)
Using recently published, high-precision pi+pi- cross section data by the BABAR experiment from the analysis of e+e- events with high-energy photon radiation in the initial state, we reevaluate the lowest order hadronic contribution a_mu[had,LO] to the anomalous magnetic moment of the muon. We employ newly developed software featuring improved data interpolation and averaging, more accurate error propagation and systematic validation. [...]
