Overview

Analysis reveals factorial enhancements in power expansion and OPE in super-renormalizable QFTs, suggesting deeper structural insights.

Key Points

  • Factorial enhancements in high power terms indicate significant IR sensitivity in coefficient functions.
  • The analysis shows that vacuum condensates play a crucial role in canceling IR divergences.
  • In super-renormalizable theories, high-order behavior affects both coupling constants and power expansion concurrently.
  • The findings suggest a divergence in the momentum-space power expansion due to factorial growths.
