What is a photon? What is an elementary particle? What is mass?

A photon is single-particle exitation of the Maxwell 4-potential field which
itself is a real representation (i.e. its own uncharged antiparticle) of the
adjoint representation of the U(1) gauge group which also forms a massless
spin-1 unitary representation of the Poincare' group.

When a particle transfers momentum to another particle so that
'heating is done' the momentum is said to transfer by
electromagnetic force, at least at one level of explanation.
Feynman was fond of charting transactions of several kinds.
How would he have shown the transfer?

Dumb question; Is it by means of a photon?
If not, then what?
