Implication

Analysis reveals local scale invariance violations in quantum field theory, suggesting conformal theory may exhibit quantum corrections.

Key Points

  • Local scale invariance violations impact quantum field theory, suggesting a broader theoretical framework.
  • The relation between Weyl anomalies and the trace anomaly is examined in depth, showing intricate connections.
  • Observational study of the trace anomaly in phi^4 theory highlights its behavior up to second order in interactions.
  • Findings indicate conformal theories may still show quantum corrections through Weyl transformations.
