We study the properties of the poles of the resummed graviton propagator obtained by resumming bub- ble matter diagrams which correct the classical graviton prop- agator.

In particular, when modeled with a Breit–Wigner dis- tribution, they have a well-defined gravitational radius. The probability that the resonance is inside its own gravitational radius, and thus that it is a black hole, is about one half. Our results confirm the interpretation of these poles as black hole precursors.

Abstract
We study the properties of the poles of the resummed graviton propagator obtained by resumming bub- ble matter diagrams which correct the classical graviton prop- agator. These poles have been previously interpreted as black holes precursors. Here, we show using the horizon wave- function formalism that these poles indeed have properties which make them compatible with being black hole precur- sors. In particular, when modeled with a Breit–Wigner dis- tribution, they have a well-defined gravitational radius. The probability that the resonance is inside its own gravitational radius, and thus that it is a black hole, is about one half. Our results confirm the interpretation of these poles as black hole precursors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
