Dep inelastic scattering with graviton as propogater

[raj07]

consider deep inelastic scattering of e-p.assuming that a graviton acts as a propogater in this interaction how would it effect the structure functions of the proton.now we have a spin 2(graviton) instead of the usual spin 1(photon).basically what is the effect of this spin change on the structure functions of proton.

what is the effect of this spin change on the structure functions of proton.

You would get more elaborate Lorentz structures, therefore richer form factors and hence essentially more information on the proton structure. Namely, you would be sensitive to the distributions of masses, angular momentum and shear forces.
