Analytical results for hadronic contributions to the muon g2
Abstract
This talk discusses two analytical calculations relevant for the Standard Model calculation of the muon g2. The first part is the recent derivation of the quarkloop as the first term in a welldefined operatorproduct expansion for the shortdistance part of the hadronic lightbylight contribution, as well as the calculation of the next term. The second part is the calculation of finite volume effects relevant for lattice QCD calculations of the electromagnetic contribution to the lowestorder hadronic vacuumpolarization contribution and the proof they only start at 1/L^3.
