Studies of e+e- -> Zgamma -> mu+ mu- gamma events at sqrt{s} = 189-208 GeV
Radiative returns to the Z peak decaying to muon pairs are selected at 189 to 208 GeV centre-of-mass energies, and event kinematic variables are analysed . The results are interpreted in terms of a possible bias of the Z mass peak position, or of a shift in the LEP centre-of-mass energy, yielding De...
