We analyse a new ${\cal N}=1$ string tree level correction at ${\cal O}(\alpha'^2)$ to the K\"ahler potential of the volume moduli of type IIB Calabi-Yau flux compactification found recently by Grimm, Savelli and Weissenbacher~\cite{Grimm:2013gma} and its impact on the moduli potential. We find that it imposes a strong lower bound the Calabi-Yau volume in the Large Volume Scenario of moduli stabilisation. For KKLT-like scenarios we find that consistency of the action imposes an upper bound on the flux superpotential $|W_0|\lesssim 10^{-3}$, while parametrically controlled survival of the KKLT minimum needs extreme tuning of $W_0$ close to zero. We also analyse the K\"ahler uplifting mechanism showing that it can operate on Calabi-Yau manifolds where the new correction is present and dominated by the 4-cycle controlling the overall volume if the volume is stabilised at values $\mathcal{V} \gtrsim 10^3$. We discuss the phenomenological implication of these bounds on $\mathcal{V}$ in the various scenarios.

Original abstract

We analyse a new ${\cal N}=1$ string tree level correction at ${\cal O}(\alpha'^2)$ to the K\"ahler potential of the volume moduli of type IIB Calabi-Yau flux compactification found recently by Grimm, Savelli and Weissenbacher~\cite{Grimm:2013gma} and its impact on the moduli potential. We find that it imposes a strong lower bound the Calabi-Yau volume in the Large Volume Scenario of moduli stabilisation. For KKLT-like scenarios we find that consistency of the action imposes an upper bound on the flux superpotential $|W_0|\lesssim 10^{-3}$, while parametrically controlled survival of the KKLT minimum needs extreme tuning of $W_0$ close to zero. We also analyse the K\"ahler uplifting mechanism showing that it can operate on Calabi-Yau manifolds where the new correction is present and dominated by the 4-cycle controlling the overall volume if the volume is stabilised at values $\mathcal{V} \gtrsim 10^3$. We discuss the phenomenological implication of these bounds on $\mathcal{V}$ in the various scenarios.

Similarly, [ref] recently described how other Kähler potential corrections affect the stabilization of classical moduli; much of their analysis applies directly to our results, since both sets of corrections to the Kähler potential have the same scaling with compactification volume in the large-volume limit.

However the corrections of [ref] were of order $α'^2 g_s^2$ and had overall numerical coefficients of $O(1)$, while here we find that the overall coefficients in Eqs. ([ref]) and ([ref]) are neither $O(1)$ nor feature suppression by extra powers of $g_s≪1$.

Note that there is a peculiar relation between the volumes of the base $B_3$ and the CY $X_3$ in the case of $ℂℙ_11169^4[18]$ that was already discussed extensively in [ref] : The triple self intersection $D_5 ∩D_5 ∩D_5$ lies on the 4-cycle defined by $ξ= 0$, i.e., the cycle that is wrapped by the O7 plane.

An additional source of vacuum energy is necessary to reach zero vacuum energy. * In 'Kähler uplifting', we can play off the $O(α'^3)$-correction to the volume moduli Kähler potential and a non-perturbative superpotential from gaugino condensation on stacked D7-branes in a different way than in the LVS [ref] .
