• -coupled to the Majorana fermion γ, cf. Equation 4. At this stage, it is convenient to trace out the ΨS,2 spinor field. As a result, the SAC is described in terms of only one spinor field, Ψ ≡ ΨS,1, which however is still coupled to the Majorana field γ. After some algebra, we obtain the effective action
