String condensation and high energy graviton scattering

A simple model of the quantum mechanics of a nucleating particle in the recently proposed string condensation mechanism is presented. This is based on a universal mechanical gauge field related to the string condensate, which behaves as a kind of fluid. String condensation is conjectured to prevent the formation of closed horizons in situations of extreme compression and thereby enable unitarity to be preserved in ultra-Planckian high energy scattering. A comparison is made with graviton scattering in the Dvali N-portrait of black holes and the subsequent Hawking evaporation process is discussed in this context.

This gives an update on further work done on the topic presented in the talk ‘String condensation: Nemesis of Black Holes’ at Planck 2015.
