 De Sitter vacua from anti-D3-branes in type IIB LVS compactifications</a>\
 nby Roberto Valandro (Trieste U.) as part of HEP seminars TU Wien (Vienna)
 \n\n\nAbstract\nWe will begin with an introduction on moduli stabilisation
  in type IIB compactifications on CY orientifolds\, with de Sitter uplift 
 due to an anti-D3 brane. We consider a concrete setup where an anti D3-bra
 ne sits at the tip of a warped throat and the stabilised volume is exponen
 tially large as in the large volume scenario (LVS). We analyse the conditi
 ons on the parameters of the EFT such that they are in the region of valid
 ity. We illustrate our results with an explicit choice of Calabi-Yau manif
 old and D-brane configuration\, where moduli stabilisation gives rise to a
  de Sitter minimum.\n
