Elementary Particle Physics - Spin Inversion Symmetry
The Photon is interesting, it has spin 1, so the Spin Inversion Operator does not change the spin. It's invariant to SIO.
Coming back to the Graviton again, assuming charge is conserved, the Spin Inversion Operator maps it into a neutral spin 1/2 particle. The only one known is the Neutrino. So is there some deep connection between the Graviton and the Neutrino?
The Spin Inversion Operator works for the Graviton and all elementary particles in the Standard Model - except for the Higgs Boson.
