A new unitarity bound on e$^{+}$e$^{-}$ annihilation
Unitarity relates sigma /sub h/ the electron-positron annihilation cross-section into hadrons and sigma /sub mu / the cross-section into muon pairs. This relation provides much more restrictive bounds on sigma /sub h/ than the simple unitarity bounds, for the case in which the hadronic channels domi...
