In applying this result will be interested in < ∂H/∂µ >VAC+1 - < ∂H/∂µ>VAC, whence additive C numbers in H will play no role.
- This subtraction of the vacuum current is implicitly implied in all calculations made with these theories since, in the language of Feynman diagrams, one always omits diagrams in which a point connects directly with itself.
See F. J. Dyson, Phys. Rev. 75 (1949), 486[APS].
If one would include such diagrams then, of course, most quantitative results would be changed.
