DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/27/">Th
 e impact of alpha' corrections on de Sitter uplifts and warped throats</a>
 \nby Gerben Venken (University of Heidelberg\, ITP) as part of AnLy String
 s and Fields online seminars\n\n\nAbstract\nOne of the most often-used pro
 posals for constructing a de Sitter vacuum in string theory is by upliftin
 g using a puffed-up anti-D3 brane in a warped throat as done in KKLT and L
 VS. In recent years there has been much discussion about the validity and 
 control of such constructions\; more broadly\, the question of whether one
  can obtain controlled de Sitter vacua at all in string theory has come un
 der close scrutiny. In this talk I will consider puffed-up antibranes in a
  warped throat  and discuss the impact of alpha' corrections to the puffed
 -up brane worldvolume theory on the dynamics of the brane (specifically th
 e KPV process)\, what control one has over such corrections and whether su
 ch correction pose an obstruction to a de Sitter uplift or are actually a 
 blessing in disguise. Based on arXiv:2212.07437.\n
