A New de Sitter Solution with a Weakly Warped Deformed Conifold
  We revisit moduli stabilisation for type IIB flux compactifications that
include a warped throat region corresponding to a warped deformed conifold,
with an anti-D3-brane sitting at its tip. The warping induces a coupling
between the conifold's deformation modulus and the bulk volume modulus in the
K\"ahler potential. Previous works have studied the scalar potential assuming a
strong warping such that this coupling term dominates, and found that the
anti-D3-brane uplift may destabilise the conifold modulus and/or volume
modulus, unless flux numbers within the throat are large, which makes tadpole
cancellation a challenge. We explore the regime of parameter space
corresponding to a weakly-but-still warped throat, such that the coupling
between the conifold and volume moduli is subdominant. We thus discover a new
metastable de Sitter solution within the four-dimensional effective field
theory. We discuss the position of this de Sitter vacuum in the string theory
landscape and swampland.
