Pion pair production in e + e − annihilation at next-to-leading order matched to Parton Shower

Abstract The pion pair production in e + e − annihilation at flavour factories plays a crucial role in the determination of the hadronic contribution to the muon anomalous magnetic moment. The recent CMD-3 measurement of the pion form factor via energy scan displays a significant difference with the...
