Apologies if my question is confused, because I'm beginner in field theory: adding up all corrections, can we talk about an effective (at least approximate) overall mass-to-charge ratio for the electroweak or QED vacuums? Suppose we want to talk about the relative strength of electric-to-gravitational vacuum polarization effects on the QED or electroweak vacuum. I realize I might already be in speculative territory with gravitational vacuum polarization effects, but I expect there to be some ratio between the coupling constants for the vacuum, between inverse square laws that couple to the mass and the charge respectively. (For my purposes, the Newtonian limit of gravity might be sufficient, here.) I'd expect the ratio for the QED vacuum, and maybe the electroweak, to be on order of the electron's or the proton's mass-to-charge ratio, but it'd be extremely helpful if someone could point me to one or more sources for a more accurate estimate. I'm having difficulty finding this on the internet in general, perhaps because I don't know what search terms to use.
