Consider the t-channel production of a resonance from the photon and reggeon in the reflectivity basis, consisting of plane-wave states constructed to be eigenstates of the reflectivity operator.  This turns out in the case of the photon to correspond to the usual linear polarization basis |x> and |y>.  Let the x (y) linear polarization states be denoted as ε=- (ε=+).
