The discussion focuses on deep inelastic scattering (DIS) of electrons on protons, specifically analyzing the implications of using a graviton as the propagator instead of a photon. The introduction of a spin-2 graviton alters the structure functions of the proton, leading to more complex Lorentz structures and richer form factors. This change enhances sensitivity to the proton's internal distributions of mass, angular momentum, and shear forces, providing deeper insights into its structure.
PREREQUISITESParticle physicists, researchers in quantum field theory, and students studying the implications of different propagators in deep inelastic scattering.
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.raj07 said:what is the effect of this spin change on the structure functions of proton.
