Hadronic Vacuum Polarization Contribution to $g_{μ} - 2$ 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 $g_{μ} - 2$

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 $g_{μ} - 2$ . They…

Hadronic Vacuum Polarization and the MUonE proposal

David Greynat, Eduardo de Rafael

The MUonE proposal at the CERN SPS consists in extracting the value of the hadronic vacuum polarization self-energy function (HVP) from its contribution to the differential cross-s…

On axials and pseudoscalars in the hadronic light-by-light contribution to the muon $(g - 2)$

Luigi Cappiello, Oscar Cata, Giancarlo D'Ambrosio +2

Despite recent developments, there are a number of conceptual issues on the hadronic light-by-light (HLbL) contribution to the muon $(g - 2)$ which remain unresolved. One of the most…

Matching long and short distances at order $O (α_{s})$ in the form factors for $K \to π ℓ^{+} ℓ^{-}$

Giancarlo D'Ambrosio, David Greynat, Marc Knecht

At order $O (α G_{F})$ , the amplitudes for the decays $K \to π ℓ^{+} ℓ^{-}$ involve a form factor given by the matrix element of the time-ordered product of the elec…

On the amplitudes for the CP-conserving $K^{\pm} (K_{S}) \to π^{\pm} (π^{0}) ℓ^{+} ℓ^{-}$ rare decay modes

Giancarlo D'Ambrosio, David Greynat, Marc Knecht

The amplitudes for the rare decay modes $K^{\pm} \to π^{\pm} ℓ^{+} ℓ^{-}$ and $K_{S} \to π^{0} ℓ^{+} ℓ^{-}$ are studied with the aim of obtaining predictions for them, such as to enable the po…
