DESCRIPTION:Abstract  : In string models with "brane supersymmetry breakin
 g" \nexponential potentials emerge at (closed string) tree level but are n
 ot accompanied by tachyons. Potentials of this type can have interesting  
 implications for Cosmology. In simplest examples\, the logarithmic slope \
 nlies precisely at a  critical value where the scalar field is forced to c
 limb up the potential when it emerges from the Big Bang. This type of beha
 vior could also have trapped scalar fields inside potential wells. If a pr
 e-inflationary climbing phase of this type had occurred within 6-7 e-folds
  of the horizon exit for the largest observable wavelengths\, it would sup
 press power in the primordial scalar spectrum\, enhancing it in the tensor
  spectrum and superposing oscillations on both.\n\nhttp://indico.cern.ch/c
