Graviton propagator, renormalization scale and black-hole like states

Graviton propagator, renormalization scale and black-hole like states

We study the analytic structure of the resummed graviton propagator, inspired by the possible existence of black hole precursors in its spectrum. We find an infinite number of poles with positive mass, but both positive and negative effective width, and studied their asymptotic behaviour in the infi...
