SUMMARY:A new top-down model of inflation\, Theory Seminar (High Energ
 y/Cosmology)\, Marjorie Schillo\, K.U. Leuven
DESCRIPTION:I will present recent work that has succeeded in embedding
  the mechanism of Unwinding Inflation in string theory. I will review 
 Unwinding Inflation and the process of brane-flux annihilation\, in wh
 ich D-branes lower flux numbers and therefore the 4D vacuum energy.   
  A dynamical brane mediates the brane-flux annihilation as it moves ac
 ross a compact internal cycle. This mechanism has recently been extend
 ed such that many units of flux can be discharged in a “flux cascade
 .” The flux cascade can be used to substantially reduce vacuum energ
 y and give rise to 60 efolds of inflation.
