**Elementary Particle Physics - The Spin Inversion Operator**

I just had an idea for a "Spin Inversion Operator". It takes an elementary particle and inverts its spin. Example: the Graviton with spin 2 would map into a spin 1/2 particle. Likewise a spin 1/2 particle would map into a spin 2 particle.

The Photon is interesting, it has spin 1, so the Spin Inversion Operator does not change the spin. It's invariant.

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.
