In the standard model gravitron is a particle but Higgs boson is not?

The Z couples to quarks, and quarks have charge, so on loop-level, you get photon/Z interactions as well (not sure how/if they might cancel out).

Pair production at a Z would be... let's call it exotic :D.

For the neutron, if the energy is low the quark charges are practically invisible because they cancel out nearly exactly then.
Multi-GeV photons don't care about the hadronic structure and scatter at the partons.
