A Calabi-Yau database: threefolds constructed from the Kreuzer-Skarke list
A bstractKreuzer and Skarke famously produced the largest known database of Calabi-Yau threefolds by providing a complete construction of all 473,800,776 reflexive polyhedra that exist in four…

Towards string theory expectations for photon couplings to axionlike particles
ALP-photon couplings are modeled in large ensembles of string vacua and random matrix theories. In all cases, the effective coupling increases polynomially in the number of ALPs, of which hundreds or…

Solving the LHC inverse problem with dark matter observations
We investigate the utility of cosmological and astrophysical observations for distinguishing between supersymmetric theories. In particular we consider 276 pairs of models that give rise to nearly…

Twenty-five questions for string theorists
In an effort to promote communication between the formal and phenomenological branches of the high-energy theory community, we provide a description of some important issues in supersymmetric and…

Machine learning in the string landscape
TLDR
Deep data dives and conjecture generation are proposed as useful frameworks for utilizing machine learning in the landscape, and examples of each are presented.

Dark matter production mechanisms with a nonthermal cosmological history: A classification
We perform a comprehensive study of models of dark matter (DM) in a Universe with a non-thermal cosmological history, i.e with a phase of pressure-less matter domination before the onset of big-bang…

String Theory and the Dark Glueball Problem
We study cosmological constraints on dark pure Yang-Mills sectors. Dark glueballs are overproduced for large regions of ultraviolet parameter space. The problem may be alleviated in two ways: via a…

Lightest Visible-Sector Supersymmetric Particle is Likely to be Unstable.
TLDR
It is argued, based on typical properties of known solutions of string or M theory, that the lightest supersymmetric particle of the visible sector is likely to be unstable and probably not a particle with standard model quantum numbers, such as a weakly interacting massive particle.
