About CPT-conservation. If you talk about graviton then you talk about linearized GR. There is theory which tells us that all irreducible representations $\left(\frac{n}{2}, \frac{m}{2} \right) \oplus \left( \frac{m}{2}, \frac{n}{2}\right)$ of the Lorentz group is invariant under $C, P, T$ transformations. The theory of graviton (it may be defined without ...
