It has been argued that keeping LVS de Sitter constructions under control requires a negative D3-tadpole exceeding known Calabi-Yau bounds.

ds-006Active research

It has been argued that keeping LVS de Sitter constructions under control requires a negative D3-tadpole exceeding known Calabi-Yau bounds.

Why it is stated this way
This is the sharpest quantitative form of the LVS control objection: rather than disputing the scheme in principle, it derives a numerical requirement and compares it with what the known geometries supply.
Scope and limitations
A parametric constraint against currently known Calabi-Yau bounds is not a no-go theorem. The bound is on what has been catalogued, and the argument is contested by LVS proponents.

This claim is one entry in an educational, non-peer-reviewed orientation tool. It is not a consensus statement, and its epistemic status label is part of the claim — quoting the wording without the status and the limitations misrepresents it.
