Polarization effects in e + +e - →d̄+d and determination of time-like deuteron form factors

Polarization effects in the reaction e{sup +}+e{sup -}{yields}d+d have been investigated for the case of longitudinally polarized electron beam and arbitrary polarization of the produced deuteron, with the aim of a determination of the time-like complex deuteron electromagnetic form factors. General expressions of polarization observables are derived and numerical estimations have been carried out by means of various models of deuteron electromagnetic form factors, for kinematical conditions near threshold.
