Spacelike and timelike kernels for the hadronic vacuum polarization contribution to the muon lifetime

A. V. Nesterenko

The explicit expressions for the spacelike kernels $K_{\Pi }^{(2)}(Q^2)$ and $K_D^{(2)}(Q^2)$ for the hadronic vacuum polarization contribution to the muon lifetime $\Delta {\Gamma }_{\text{had}}$…
