Abstract
We discuss hadronic effects in the muonium hyperfine structure and derive a n expression for the hadronic, contribution to the hfs interval in form of the one-dimensional integral of the cross section of e+e(-) annihilation in to hadrons. Higher-order hadronic contributions are also considered. (C) 20 01 Elsevier Science B.V. All rights reserved.
