M-theory frozen singularities are (locally) $D$- or $E$-type orbifold singularities with a background fractional $C_3$-monodromy surrounding them. [...]

Math. ; Pennsylvania U.) ; Heckman, Jonathan J. (Pennsylvania U., Dept. Math. ; Pennsylvania U.) ; Hübner, Max (Pennsylvania U., Dept. Math.) ; Torres, Ethan (CERN)
The symmetry data of a $d$-dimensional quantum field theory (QFT) can often be captured in terms of a higher-dimensional symmetry topological field theory (SymTFT). [...]

Brill-Noether-general Limit Root Bundles: Absence of vector-like Exotics in F-theory Standard Models / Bies, Martin (Pennsylvania U.) ; Cvetič, Mirjam (Pennsylvania U. ; Maribor U. ; CERN) ; Donagi, Ron (Pennsylvania U.) ; Ong, Marielle (Pennsylvania U.)
Root bundles appear prominently in studies of vector-like spectra of 4d F-theory compactifications. Of particular importance to phenomenology are the Quadrillion F-theory Standard Models (F-theory QSMs). [...]

0-form, 1-form, and 2-group symmetries via cutting and gluing of orbifolds / Cvetič, Mirjam (Pennsylvania U. ; Maribor U. ; CERN ; Pennsylvania U., Dept. Math.) ; Heckman, Jonathan J. (Pennsylvania U. ; Pennsylvania U., Dept. Math.) ; Hübner, Max (Pennsylvania U.) ; Torres, Ethan (Pennsylvania U.)
Orbifold singularities of M-theory constitute the building blocks of a broad class of supersymmetric quantum field theories (SQFTs). In this paper we show how the local data of these geometries determines global data on the resulting higher symmetries of these systems. [...]

We review recent developments and outstanding questions regarding connecting the top-down UV complete physical framework of string theory with the observed physics of the Standard Model and beyond the Standard Model physics, emphasizing the global nonperturbative framework of F-theory and general lessons from UV physics. [...]

Flavor Symmetries and Automatic Enhancement in the 6d Supergravity Swampland / Cvetic, Mirjam (Pennsylvania U. ; Maribor U. ; CERN) ; Lin, Ling (CERN) ; Turner, Andrew P. (Pennsylvania U.)
We argue for the quantum-gravitational inconsistency of certain 6d $\mathcal{N}=(1,0)$ supergravity theories, whose anomaly-free gauge algebra $\mathfrak{g}$ and hypermultiplet spectrum $M$ were observed in arxiv:2012.01437 to be realizable only as part of a larger gauge sector $(\mathfrak{g}' \supset \mathfrak{g}, M' \supset M)$ in F-theory. To detach any reference to a string theoretic method of construction, we utilize flavor symmetries to provide compelling reasons why the vast majority of such $(\mathfrak{g},M)$ theories are not compatible with quantum gravity constraints, and how the "automatic enhancement" to $(\mathfrak{g}', M')$ remedies this. [...]

Gauge group topology of 8D Chaudhuri-Hockney-Lykken vacua / Cvetic, Mirjam (Pennsylvania U. ; Maribor U.) ; Dierigl, Markus (Munich U., ASC) ; Lin, Ling (CERN) ; Zhang, Hao Y. (Pennsylvania U.)
Compactifications of the CHL string to eight dimensions can be characterized by embeddings of root lattices into the rank 12 momentum lattice $\Lambda_M$, the so-called Mikhailov lattice. Based on this data, we devise a method to determine the global gauge group structure including all $U(1)$ factors. [...]

Higher-form symmetries and their anomalies in M-/F-theory duality / Cvetic, Mirjam (Pennsylvania U. ; Maribor U.) ; Dierigl, Markus (Munich U., ASC) ; Lin, Ling (CERN) ; Zhang, Hao Y. (Pennsylvania U.)
We explore higher-form symmetries of M- and F-theory compactified on elliptic fibrations, determined by the topology of their asymptotic boundaries. The underlying geometric structures are shown to be equivalent to known characterizations of the gauge group topology in F-theory via Mordell--Weil torsion and string junctions. [...]

Machine Learning and Algebraic Approaches towards Complete Matter Spectra in 4d F-theory / Bies, Martin (Oxford U., Inst. Math.) ; Cvetič, Mirjam (Pennsylvania U. ; Pennsylvania U., Dept. Math. ; Maribor U.) ; Donagi, Ron (Pennsylvania U. ; Pennsylvania U., Dept. Math.) ; Lin, Ling (CERN) ; Liu, Muyang (Pennsylvania U.) ; Ruehle, Fabian (CERN ; Oxford U., Theor. Phys.)
Motivated by engineering vector-like (Higgs) pairs in the spectrum of 4d F-theory compactifications, we combine machine learning and algebraic geometry techniques to analyze line bundle cohomologies on families of holomorphic curves. To quantify jumps of these cohomologies, we first generate 1.8 million pairs of line bundles and curves embedded in $dP_3$, for which we compute the cohomologies. [...]

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..
