Question

How does the Newton's constant get renormalized in Quantum Gravity with matter?

Answer 1

Hey mate ^_^

In quantum gravity with matter, say e.g. RR + ∂ϕμ∂ϕμ, even the one loop correction is non-renormalizable..... I am sure many smart people have already worked on this, so I would like some references which contain classifications of these divergences.....

Answer 2

Héy hii...

So, Thé ÃnSwer is -- In quantum gravity with matter, say e.g. RR + ∂ϕμ∂ϕμ∂ϕμ∂ϕμ, even the one loop correction is non-renormalizable. I am sure many smart people have already worked on this, so I would like some references which contain classifications of these divergences. I am interested in the (divergent) term which renormalizes GNGN at 1-loop. The diagram I am referring to, is the graviton propagator, with ϕϕrunning in the loop. A full answer discussing these divergences is also welcome. Thanks in advance.
