"Brane Inflation, D-strings and fermion zero modes"

Recent developments in string theory suggest that inflation could arise in brane anti-brane systems or in a theory containing a D3/D7 brane. The interbrane distance plays the role of the inflaton. D-strings seem to arise naturally at the end of inflation in most models. I will discuss recent progress in brane inflation, concentrating on the D3/D7 system. I will analyse cosmic strings arising from an effective supergravity theory based on the D3/D7 brane model and calculate the corresponding zero modes. Physical constraints arising will be discussed.
