About this document
Causality, Analyticity and An IR Obstruction To UV Completion by gladstneholmes is a document available to read on EtoBox.
The document discusses the limitations of certain low-energy effective field theories that, while appearing consistent, exhibit macroscopic non-locality and cannot be embedded in any ultraviolet (UV) complete theory satisfying analyticity constraints. It highlights that the positivity of leading irrelevant operators is crucial for maintaining Lorentz-invariance and causality, with violations leading to superluminal fluctuations and an inability to define local evolution. The authors argue that experimental
