Seminar Room 1, Newton Institute

Abstract

Cosmic superstring networks contain strings of multiple tensions and Y-junctions. Depending on the magnitude of the fundamental string coupling, the stress-energy power spectrum of the scaling network is dominated either by populous light F strings, or rare heavy D strings. It may be possible to distinguish between these two regimes with future observations of CMB polarization.
