description

Abstract We consider the spin orientation of the final Z bosons for the processes in the Standard Model. We demonstrate that at the threshold energies of these processes the analytical expressions for the Z boson polarization vectors and alignment tensors coincide ( e + e − → Z H , Z γ ) or are very similar ( e + e − → Z Z ). In addition, we present interesting symmetry properties for the spin orientation parameters.
