String geometry potential and the true vacuum conjecture

Establish that the potential for string backgrounds—defined as the “classical” potential of string geometry theory restricted to the perturbative vacua—faithfully represents the string theory landscape and prove that its global minimum corresponds to the true vacuum of string theory.

Background

The paper studies a framework, string geometry theory, proposed as a non‑perturbative formulation of string theory. Within this framework, the authors define a potential restricted to perturbative vacua—the potential for string backgrounds—and use it to compare and select among compactification models.

They repeatedly motivate and utilize this potential as a tool to identify preferred vacua, but its interpretation as representing the full string landscape and selecting the true vacuum is stated as a conjecture rather than a proven result. Validating this identification would provide a principled, non‑perturbative criterion for vacuum selection in string theory.

References

Therefore, it is reasonable to conjecture that the ``classical'' potential restricted to the perturbative vacua, called the potential for string backgrounds, in string geometry theory represent the string theory landscape and the minimum of the potentials gives the true vacuum in string theory .
