Massive Type IIB Superstrings Part I: 3- and 4-Point Amplitudes
Nicholas Agia
We present the 3- and 4-point tree-level scattering amplitudes involving first-massive states in closed Type IIB superstring theory, computed in the Minkowski vacuum. In particular…

Low-Lying Cosmic String Spectrum and Background Fields in Effective String Theory
Nicholas Agia
We present a detailed analysis of the cosmic string spectrum. Explicit solutions are numerically found using Mathematica and presented here for the lowest-lying supported modes. Mo…
