Multi-dimensional chaos II: String scattering amplitudes, curve repulsion, and RMT
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
Multi-dimensional chaos refers to processes described by erratic functions of several dynamical variables. In this letter we analyze the string scattering amplitudes of highly-exci…

One-loop mass corrections of interacting string states
Lorenzo Grimaldi, Massimo Bianchi, Maurizio Firrotta
The free string spectrum is highly degenerate, with a degeneracy that grows exponentially with the mass. Turning on a non-vanishing string coupling introduces interactions, r…

One-loop mass corrections and decay widths of Type II heavy string states
Massimo Bianchi, Maurizio Firrotta, Lorenzo Grimaldi
We approach a systematic investigation of the one-loop mass corrections to (super-)string massive higher-spin states. While the imaginary part of the relevant amplitudes is finite,…
