Studies of e+e- -> Zgamma -> mu+ mu- gamma events at sqrt{s} = 189-208GeV
Radiative returns to the Z peak decaying to muon pairs are selected at LEP2 energies from 189 to 208GeV centre-of-mass energies , and analysed in search for discrepancies between data and Monte Carlo in the distribution of the event kinematic variables.

| Sumario: | Radiative returns to the Z peak decaying to muon pairs are selected at LEP2 energies from 189 to 208GeV centre-of-mass energies , and analysed in search for discrepancies between data and Monte Carlo in the distribution of the event kinematic variables. The results are interpreted in terms of a possible shift of the Z mass peak position, or of the LEP centre-of-mass energy. |
