4. HLS Approach to the muon g-2 evaluation

Mr Maurice Benayoun (LPNHE des Universites Paris 6 et 7)

The HLS model supplemented with suitable SU(2)/SU(3) breaking schemes allows to build a phenomenological model which encompasses six e+e- annihilation channels (pi+ pi-, K+ K-, K0 K0bar, pi0 gamma, eta gamma, pi+ pi-pi0), the dipion spectrum in the tau decay and a few more meson annihilation partial width information. One thus yields a simultaneous description of all these physics...

5. Towards analytic four-loop corrections to the anomalous magnetic moment of leptons

Prof. Matthias Steinhauser (KIT)

The anomalous magnetic moments of the electron and muon have been measured to high accuracy. On the theory-side they are predicted including quantum corrections up to five loops. Whereas three-loop corrections are known analytically the four- and five-loop terms are only available in numerical form. In this talk first analytic four-loop results are presented. As a byproduct the...

12. Hadronic vacuum polarization contribution to g-2 from the lattice

Prof. Maarten Golterman (San Francisco State University)

11/09/2013, 11:30

In this talk, I will discuss the status of lattice computations of the leading hadronic contribution to the muon anomalous magnetic moment. The focus will be on methods that can help making the lattice determination competitive with the value obtained from the e+e- cross section.
