Computational Mirror Symmetry / Demirtas, Mehmet (IAIFI, Cambridge ; Northeastern U.) ; Kim, Manki (MIT, LNS) ; McAllister, Liam (Cornell U.) ; Moritz, Jakob (Cornell U. ; CERN) ; Rios-Tascon, Andres (Cornell U.)
We present an efficient algorithm for computing the prepotential in compactifications of type II string theory on mirror pairs of Calabi-Yau threefolds in toric varieties. Applying this method, we exhibit the first systematic computation of genus-zero Gopakumar-Vafa invariants in compact threefolds with many moduli, including examples with up to 491 vector multiplets..

Moduli space reconstruction and Weak Gravity / Gendler, Naomi (Cornell U.) ; Heidenreich, Ben (Massachusetts U., Amherst) ; McAllister, Liam (Cornell U.) ; Moritz, Jakob (Cornell U. ; CERN) ; Rudelius, Tom (UC, Berkeley)
We present a method to construct the extended Kähler cone of any Calabi-Yau threefold by using Gopakumar-Vafa invariants to identify all geometric phases that are related by flops or Weyl reflections. In this way we obtain the Kähler moduli spaces of all favorable Calabi-Yau threefold hypersurfaces with $h^{1,1} \le 4$, including toric and non-toric phases. [...]

Candidate de Sitter Vacua / McAllister, Liam (Cornell U., Phys. Dept.) ; Moritz, Jakob (CERN) ; Nally, Richard (Cornell U., Phys. Dept.) ; Schachner, Andreas (Cornell U., Phys. Dept. ; Munich U., ASC)
We construct compactifications of type IIB string theory that yield, at leading order in the $\alpha^\prime$ and $g_s$ expansions, de Sitter vacua of the form envisioned by Kachru, Kallosh, Linde, and Trivedi. [...]

Classifying Calabi-Yau threefolds using infinite distance limits / Grimm, Thomas W. (Utrecht U.) ; Ruehle, Fabian (CERN ; Oxford U., Theor. Phys.) ; van de Heisteeg, Damian (Utrecht U.)
We present a novel way to classify Calabi-Yau threefolds by systematically studying their infinite volume limits. Each such limit is at infinite distance in Kahler moduli space and can be classified by an associated limiting mixed Hodge structure. [...]

Moduli-dependent Calabi-Yau and SU(3)-structure metrics from Machine Learning / Anderson, Lara B. (Virginia Tech.) ; Gerdes, Mathis (Munich U., ASC) ; Gray, James (Virginia Tech.) ; Krippendorf, Sven (Munich U., ASC) ; Raghuram, Nikhil (Virginia Tech.) ; Ruehle, Fabian (CERN ; Oxford U., Theor. Phys.)
We use machine learning to approximate Calabi-Yau and SU(3)-structure metrics, including for the first time complex structure moduli dependence. Our new methods furthermore improve existing numerical approximations in terms of accuracy and speed [...]

Constraints on Standard Model Constructions in F-theory / Cvetic, Mirjam (Pennsylvania U. ; Maribor U.) ; Halverson, James (Northeastern U.) ; Lin, Ling (CERN) ; Long, Cody (Northeastern U. ; Cornell U., Phys. Dept.)
We argue that the following three statements cannot all be true: (i) our vacuum is a type IIB / F-theory vacuum at moderate-to-large $h^{1,1}$, (ii) the $\alpha'$-expansion is controlled via the supergravity approximation, à la the KKLT and LVS scenarios, and (iii) there are no additional gauged sectors from seven-branes. Since nearly all known globally consistent F-theory models with the exact chiral spectrum of the Standard Model and gauge coupling unification occur at moderate $h^{1,1}$, this finding calls for new moduli stabilization scenarios or/and a rich seven-brane dark sector..

The Apollo ATCA Design for the CMS Track Finder and the Pixel Readout at the HL-LHC / CMS Collaboration
The challenging conditions of the High-Luminosity LHC require tailored hardware designs for the trigger and data acquisition systems. The Apollo platform features a ``Service Module'' with a powerful system-on-module computer that provides standard ATCA communications and an application-specific ``Command Module''s with large FPGAs and high speed optical fiber links.
