DESCRIPTION:Speakers: Lucas Leung (Oxford University)\n\nString compactifi
 cations naturally lead to a large number of massless scalar moduli fields 
 in the low-energy effective theory which must be stabilised in any serious
  attempts of reproducing realistic string models of particle physics. Whil
 st landscapes of heterotic string models that reproduce the standard model
  spectrum have been well studied\, heterotic moduli stabilisation remains 
 much less developed than analogous mechanisms in other string theories. In
  this talk I will aim to provide a review of moduli stabilisation in strin
 g theory and highlight the challenges in heterotic theories compared to it
 s analogous Type IIB case. I will then address the size of the flux superp
 otential W0 in heterotic theories\, and provide no-go theorems and explici
 t examples for small-W0 vacua in different regions of complex structure mo
 duli space. This talk is based on a forthcoming publication with Andrei Co
 nstantin\, Andre Lukas and Burt Ovrut.\n\nhttps://indico.uu.se/event/2119/
