SUMMARY:Corrections to the LARGE-Volume Scenario\, Theory Seminar (Hig
 h Energy/Cosmology)\, Daniel Junghans\, Harvard University
DESCRIPTION:We argue that de Sitter vacua in the LARGE-volume scenario
  of type IIB string theory are vulnerable to various unsuppressed curv
 ature\, warping and g_s corrections. We discuss how these corrections 
 affect the moduli vevs\, the vacuum energy and the moduli masses. Our 
 analysis reveals that the corrections are parametrically larger in the
  relevant expressions than one might have guessed from their suppressi
 on in the off-shell potential. Some corrections appear without any par
 ametric suppression at all\, which makes them particularly dangerous f
 or candidate de Sitter vacua. Other types of corrections can in princi
 ple be made small for appropriate parameter choices. However\, we show
  in an explicit model that this is never possible for all corrections 
 at the same time when the vacuum energy is positive.
