Abstract

Polarizations of $Z^{0}$ and γ in the reaction $e^{+}$ $e^{-}$ → $Z^{0}$ γ near the $Z^{0}$ peak are obtained through the density matrix of $Z^{0}$ and Stokes parameters of γ, respectively. Their dependence on the linear polarizations of incident electron-positron beams and their influence on the decay of $Z^{0}$ into two spin-(1/2 fermions f and f¯ are discussed in the standard model. It is shown that the longitudinal polarization of incident electron beam can enhance the circular polarization of the outgoing photon beam.
