Does the graviton move at the speed of light in any reference frame?

Does the graviton move at the speed of light in any reference frame?

Thanks,

Yes, provided that the speed (or more precisely, velocity) is defined in a general-relativistic covariant way.

Is there a Graviton?

In the standard model it says that there could be such thing as a graviton. But i would think that if a photon is moving at the cosmological constant (speed of light), then all elementary gauge bosons would be moving that same speed.

I would not insist on the term "graviton" as it contains some speculations about the quantization of gravity - which is by no means complete. Instead I would talk about a "gravitational wave", which always travels at the speed of light (provided that ... refer to Demystifier)
