Possible anomalous image and image couplings and Z boson spin orientation in image Original Research Article

A method based on a general relativistic spin-1 density matrix formalism has been used to find analytically the possible CP-conserving anomalous image and image couplings corrections to the polarization vector and the alignment tensor for the Z boson in the process image with longitudinally polarized initial beams. The role of longitudinal polarization of the initial beams for disentangling different sets of couplings has been analysed.
