Spacelike and timelike kernels for the hadronic vacuum polarization contribution to the muon lifetime
Abstract
The explicit expressions for the spacelike kernels KΠ(2)(Q2) and KD(2)(Q2) for the hadronic vacuum polarization contribution to the muon lifetime ΔΓhad are derived. The obtained results enable one to evaluate ΔΓhad within such methods as lattice studies, MUonE project, and others.
