A Prelude to Ultrahigh-Energy String Excitation

Abstract

The configuration of highly-excited string states is recapitulated through ultrahigh energy, perturbative string scattering without direct recourse to the thermal string amplitude in proper reference to the possible violation of unitarity bounds, the possible macroscopic nonlocality and the possible association with the newfashioned percolation scenario. The crucial role of the order parameter of the string/black hole correspondence is then sketched from the viewpoint of string cosmology.
