Self-energy and tadpole diagrams contribute to quantum field theory propagators
Is it true that self-energy and tadpole diagrams contribute to quantum field theory propagators?
Self-energy corrections and tadpole diagrams are standard, foundational perturbative components in quantum field theory that directly modify propagators and correlation functions, making this a matter of common definition and textbook knowledge.
Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked
The claim states a foundational definition and mechanism in quantum field theory: self-energy and tadpole diagrams contribute to and modify propagators. This is a matter of textbook definition and basic QFT construction (common knowledge), so citations are not strictly required to validate the definitional claim, although relevant QFT literature like paper [0] and [8] implicitly utilize self-energy corrections in propagators.
