# A Cosmological Constant That is Too Small

@inproceedings{Demirtas2021ACC, title={A Cosmological Constant That is Too Small}, author={Mehmet S. Demirtas and Manki Kim and Liam McAllister and Jakob Moritz and Andres Rios-Tascon}, year={2021} }

We construct a vacuum of string theory in which the magnitude of the vacuum energy is < 10−123 in Planck units. Regrettably, the sign of the vacuum energy is negative, and some supersymmetry remains unbroken. ar X iv :2 10 7. 09 06 5v 1 [ he pth ] 1 9 Ju l 2 02 1

The magnitude of the vacuum expectation value of the Gukov-Vafa-Witten superpotential |W0| plays a central role in the phenomenology of type IIB flux compactifications. Recent analytical… Expand

D-instantons in Type IIA string theory on Calabi-Yau threefolds

- Physics

Type IIA string theory compactified on a Calabi-Yau threefold has a hypermultiplet moduli space whose metric is known to receive non-perturbative corrections from Euclidean D2-branes wrapped on… Expand

Analytic Periods via Twisted Symmetric Squares

We study the symmetric square of Picard-Fuchs operators of genus one curves and the thereby induced generalized Clausen identities. This allows the computation of analytic expressions for the periods… Expand

The Cosmological Constant and the String Landscape

- Physics
- 2006

Theories of the cosmological constant fall into two classes, those in which the vacuum energy is fixed by the fundamental theory and those in which it is adjustable in some way. For each class we… Expand

Abstract We prove that Weyl invariant theories of gravity possess a remarkable property which, under very general assumptions, explains the stability of flat space-time. We show explicitly how… Expand

The energy density of the vacuum, Lambda, is at least 60 orders of magnitude smaller than several known contributions to it. Approaches to this problem are tightly constrained by data ranging from… Expand

Flux Compactification

- Physics

We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological… Expand

Dynamical Breaking of Supersymmetry

We should be taking advantage of recent gains in our nonperturbative understanding of supersymmetric gauge theories to find the “standard” model of of dynamical supersymmetry breaking, and possibly… Expand

Five-brane effective action in M theory

Abstract On the world-volume of an M-theory five-brane propagates a two-form with self-dual field strength. As this field is non-Lagrangian, there is no obvious framework for determining its… Expand

Counting flux vacua

We develop a technique for computing expected numbers of vacua in gaussian ensembles of supergravity theories, and apply it to derive an asymptotic formula for the index counting all flux… Expand

Type IIA Moduli Stabilization

We demonstrate that flux compactifications of type IIA string theory can classically stabilize all geometric moduli. For a particular orientifold background, we explicitly construct an infinite… Expand

Quantization of four-form fluxes and dynamical neutralization of the cosmological constant

- Physics

A four-form gauge flux makes a variable contribution to the cosmological constant. This has often been assumed to take continuous values, but we argue that it has a generalized Dirac quantization… Expand

Computational complexity of the landscape I

It is proved that in the Bousso–Polchinski model, the problem of finding vacua of string theory which agree with data is NP complete, and this point of view is applied to the question of how early cosmology might select a vacuum. Expand
