Theoretical constraints on brane inflation and cosmic superstring radiation

Understand

We analyze theoretical constraints on the consistency of brane inflation leading to cosmic superstring formation and on the subsequent radiation of these cosmic superstrings.

• We first investigate the implications of recently elucidated supergravity constraints on models of brane inflation.
• We show that both D3/D7 and D3/anti-D3 brane inflation are subject to non-trivial constraints.
• Both models can be shown to satisfy those constraints, but for the case of D3/D7 there may be important consequences for the inflationary mechanism.
