{"knowledge_schema": {"broad_category": "Physics \u2192 Theoretical Physics \u2192 Quantum Field Theories", "refinement": "This problem pertains to the behavior of different physical theories at high energy scales and their need for regularization to handle infinities or divergences.", "specific_scope": "The focus is on identifying which of the listed theories can operate at high energies without requiring regularization techniques to manage divergences.", "goal": "Determine which physical theory is free from the need for regularization at high energies."}, "summary": "This question explores the characteristics of various physical theories in the context of high-energy behavior and the necessity for regularization. Among the options provided, Superstring Theory is identified as the theory that does not require regularization at high energies, unlike Classical Electrodynamics, Quantum Electrodynamics, and Quantum Chromodynamics, which all encounter issues that necessitate regularization to address divergences."}
