SUMMARY

Supergravity (SUGRA) is crucial for string theory and M-theory but is generally considered non-renormalizable. The discussion centers on the potential for SUGRA to be asymptotically safe in a non-perturbative context, similar to the arguments presented by Reuter regarding Einstein-Hilbert (EH) action. A key point raised is the distinction between on-shell techniques, typically required for studying the finiteness of SUGRA, and the off-shell Green's functions employed by Reuter.

PREREQUISITES
  • Understanding of supergravity (SUGRA) principles
  • Familiarity with string theory and M-theory
  • Knowledge of renormalization concepts in quantum field theory
  • Awareness of on-shell and off-shell techniques in theoretical physics
NEXT STEPS
  • Research the implications of asymptotic safety in quantum gravity
  • Study Reuter's approach to the Einstein-Hilbert action
  • Explore on-shell versus off-shell techniques in quantum field theory
  • Investigate current advancements in supergravity finiteness
USEFUL FOR

The discussion is beneficial for theoretical physicists, particularly those specializing in quantum gravity, string theory researchers, and anyone exploring the renormalization properties of supergravity.

That sugra is very important to string theory and m theory. But, it seems to be non renormalizable. But could it asymptotic safe, non perturbatively, like Reuter argues for EH action?

Do you know something about the current status?

I don't know.

But my understanding was always that studying finiteness of SUGRA requires on-shell techniques, whereas Reuter uses off-shell Greens functions.
