Hadronic Vacuum Polarization Contribution to as a function of the external lepton mass
David Greynat, Eduardo de Rafael
The hadronic vacuum polarization contribution to the anomalous magnetic moment of a lepton is considered as a function of the lepton mass. We show how the analyticity properties of…
On the Time Momentum Representation of Hadronic Vacuum Polarization and
David Greynat, Eduardo de Rafael
We propose a new set of model independent approximants adapted to the time momentum representation (TMR) of hadronic vacuum polarization (HVP) and its contribution to . They…
The Mellin-Barnes Approach to Hadronic Vacuum Polarization and
Jérôme Charles, David Greynat, Eduardo de Rafael
It is shown that with a precise determination of a few derivatives of the hadronic vacuum polarization (HVP) self-energy function at , from lattice QCD (LQCD) or fr…
Hadronic Vacuum Polarization in QCD and its Evaluation in the Euclidean
Eduardo de Rafael
We discuss a new technique to evaluate integrals of QCD Green's functions in the Euclidean based on their Mellin-Barnes representation. We present as a first application the evalua…
