Is SUGRA N=1 in 11D asymptotic safe a la Reuter?

  • Thread starter MTd2
  • Start date
In summary, SUGRA N=1 in 11D asymptotic safe a la Reuter is a supersymmetric theory in 11 dimensions proposed to be asymptotically safe by physicist Martin Reuter. The "N=1" in SUGRA N=1 refers to the amount of supersymmetry present, and it is related to string theory as a low energy limit of Type IIA string theory. The significance of the theory being asymptotically safe lies in its potential to provide a renormalizable theory of gravity, resolving conflicts between general relativity and quantum mechanics. While there is ongoing research and debate on its validity, more evidence is needed to definitively confirm its status as an asymptotically safe theory.

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.
 

1. What is SUGRA N=1 in 11D asymptotic safe a la Reuter?

SUGRA N=1 in 11D asymptotic safe a la Reuter refers to a specific supersymmetric theory called Supergravity (SUGRA) in 11 dimensions, which has been proposed to be asymptotically safe based on the research of physicist Martin Reuter. Asymptotic safety is a theory in quantum gravity that suggests the existence of a fixed point in the renormalization group flow, allowing for a consistent and well-defined theory of gravity.

2. What does the "N=1" in SUGRA N=1 mean?

The "N=1" in SUGRA N=1 refers to the amount of supersymmetry present in the theory. In this case, it means that there is one supersymmetry generator, making it a minimal supersymmetric theory.

3. How is SUGRA N=1 in 11D related to string theory?

SUGRA N=1 in 11D is a low energy limit of string theory, specifically Type IIA string theory. This means that at low energies, the behavior of SUGRA N=1 in 11D matches that of Type IIA string theory, providing a connection between the two theories.

4. What is the significance of the theory being asymptotically safe?

The idea of asymptotic safety in quantum gravity is significant because it suggests the possibility of a renormalizable theory of gravity, which has been a long-standing challenge in theoretical physics. This could potentially resolve the conflicts between general relativity and quantum mechanics and provide a more complete understanding of the universe.

5. What is the current evidence for SUGRA N=1 in 11D being asymptotically safe?

There is still ongoing research and debate about the validity of SUGRA N=1 in 11D being asymptotically safe. Some studies have shown promising results, but it is still a relatively new and untested theory. More research and experimentation is needed to definitively determine its validity.
