DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/6/">(Ca
 ncelled) Corrections to the LARGE-Volume Scenario</a>\nby Daniel Junghans 
 (Harvard U.) as part of AnLy Strings and Fields online seminars\n\n\nAbstr
 act\nWe argue that de Sitter vacua in the LARGE-volume scenario of type II
 B string theory are vulnerable to various unsuppressed curvature\, warping
  and g_s corrections. We discuss how these corrections affect the moduli v
 evs\, the vacuum energy and the moduli masses. Our analysis reveals that t
 he corrections are parametrically larger in the relevant expressions than 
 one might have guessed from their suppression in the off-shell potential. 
 Some corrections appear without any parametric suppression at all\, which 
 makes them particularly dangerous for candidate de Sitter vacua. Other typ
 es of corrections can in principle be made small for appropriate parameter
  choices. However\, we show in an explicit model that this is never possib
 le for all corrections at the same time when the vacuum energy is positive
