    "abstract": "We show how to derive relativistic, unitary, gauge invariant, and charge\nconserving three-dimensional scattering equations for a system of hadrons\ninteracting with an electromagnetic field. In the method proposed, the\nspectator equations describing the strong interactions of the hadrons are\ngauged using our recently introduced gauging of equations method. A key\ningredient in our model is the on-mass-shell particle propagator. We discuss\nhow to gauge this on-mass-shell propagator so that both the Ward-Takahashi and\nWard identities are satisfied. We then demonstrate our gauging procedure by\nderiving the gauge-invariant three-dimensional expression for the deuteron\nphotodisintegration amplitude within the spectator approach.",
