In Carrolls notes on General Relativity, it is said that the general formula for finding the spin number of a particle is $$\frac{360°}{\theta}$$ where ##\theta## is the angle of rotation, after which the state of the field describing the particle returns to its original state polarization. He argues that the graviton (if it exists) should have spin-2, because after a ##180°## rotation the polarization of the field describing the plane wave returns to its starting state.
My question is, for particles which have spin zero, it means that their fields never return to their original state?
