Abstract: One of the most often-used proposals for constructing a de Sitter vacuum in string theory is by uplifting using a puffed-up anti-D3 brane in a warped throat as done in KKLT and LVS. 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 under 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 the KPV process), what control one has over such corrections and whether such correction pose an obstruction to a de Sitter uplift or are actually a blessing in disguise. Based on arXiv:2212.07437.
