Chiral spectrum of the universal tuned 4D F-theory model
Patrick Jefferson, Washington Taylor, Andrew P. Turner
We use the recently developed methods of 2108.07810 to analyze vertical flux backgrounds and associated chiral matter spectra in the 4D universal $(\text{SU}(3) \times \text{SU}(2)…
Large U(1) charges from flux breaking in 4D F-theory models
Shing Yan Li, Washington Taylor
We study the massless charged spectrum of U(1) gauge fields in F-theory that arise from flux breaking of a nonabelian group. The U(1) charges that arise in this way can be very lar…
Gauge symmetry breaking with fluxes and natural Standard Model structure from exceptional GUTs in F-theory
Shing Yan Li, Washington Taylor
We give a general description of gauge symmetry breaking using vertical and remainder fluxes in 4D F-theory models. The fluxes can break a geometric gauge group to a smaller group…
Snowmass White Paper: String Theory and Particle Physics
Mirjam Cvetic, James Halverson, Gary Shiu +1
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…
Identifying equivalent Calabi--Yau topologies: A discrete challenge from math and physics for machine learning
Vishnu Jejjala, Washington Taylor, Andrew Turner
We review briefly the characteristic topological data of Calabi--Yau threefolds and focus on the question of when two threefolds are equivalent through related topological data. Th…
Natural F-theory constructions of Standard Model structure from flux breaking
Shing Yan Li, Washington Taylor
We describe a broad class of 4D F-theory models in which an gauge group is broken through fluxes to the Standard Model gauge group. These models are ubiquitous in the 4D F-th…
Charge completeness and the massless charge lattice in F-theory models of supergravity
David R. Morrison, Washington Taylor
We prove that, for every 6D supergravity theory that has an F-theory description, the property of charge completeness for the connected component of the gauge group (meaning that a…
Chiral matter multiplicities and resolution-independent structure in 4D F-theory models
Patrick Jefferson, Washington Taylor, Andrew P. Turner
Motivated by questions related to the landscape of flux compactifications, we combine new and existing techniques into a systematic, streamlined approach for computing vertical flu…
Automatic Enhancement in 6D Supergravity and F-theory Models
Nikhil Raghuram, Washington Taylor, Andrew P. Turner
We observe that in many F-theory models, tuning a specific gauge group and matter content under certain circumstances leads to an automatic enhancement to a larger gauge gr…
General F-theory models with tuned symmetry
Nikhil Raghuram, Washington Taylor, Andrew P. Turner
We construct a general form for an F-theory Weierstrass model over a general base giving a 6D or 4D supergravity theory with gauge group $(\operatorname{SU}(3) \times \operatorname…
Fibration structure in toric hypersurface Calabi-Yau threefolds
Yu-Chien Huang, Washington Taylor
We find through a systematic analysis that all but 29,223 of the 473.8 million 4D reflexive polytopes found by Kreuzer and Skarke have a 2D reflexive subpolytope. Such a subpolytop…
Generic construction of the Standard Model gauge group and matter representations in F-theory
Washington Taylor, Andrew P. Turner
We describe general classes of 6D and 4D F-theory models with gauge group . We prove t…
Generic matter representations in 6D supergravity theories
Washington Taylor, Andrew P. Turner
In six-dimensional supergravity, there is a natural sense in which matter lying in certain representations of the gauge group is "generic," in the sense that other "exotic" matter…
Mirror symmetry and elliptic Calabi-Yau manifolds
Yu-Chien Huang, Washington Taylor
We find that for many Calabi-Yau threefolds with elliptic or genus one fibrations mirror symmetry factorizes between the fiber and the base of the fibration. In the simplest exampl…
Large U(1) charges in F-theory
Nikhil Raghuram, Washington Taylor
We show that massless fields with large abelian charges (up to at least q = 21) can be constructed in 6D F-theory models with a U(1) gauge group. To show this, we explicitly constr…
On the prevalence of elliptic and genus one fibrations among toric hypersurface Calabi-Yau threefolds
Yu-Chien Huang, Washington Taylor
We systematically analyze the fibration structure of toric hypersurface Calabi-Yau threefolds with large and small Hodge numbers. We show that there are only four such Calabi-Yau t…
Comparing elliptic and toric hypersurface Calabi-Yau threefolds at large Hodge numbers
Yu-Chien Huang, Washington Taylor
We compare the sets of Calabi-Yau threefolds with large Hodge numbers that are constructed using toric hypersurface methods with those can be constructed as elliptic fibrations usi…
An infinite swampland of U(1) charge spectra in 6D supergravity theories
Washington Taylor, Andrew P. Turner
We analyze the anomaly constraints on 6D supergravity theories with a single abelian U(1) gauge factor. For theories with charges restricted to and no tensor multi…
Scanning the skeleton of the 4D F-theory landscape
Washington Taylor, Yi-Nan Wang
Using a one-way Monte Carlo algorithm from several different starting points, we get an approximation to the distribution of toric threefold bases that can be used in four-dimensio…
Exotic matter on singular divisors in F-theory
Denis Klevers, David R. Morrison, Nikhil Raghuram +1
We analyze exotic matter representations that arise on singular seven-brane configurations in F-theory. We develop a general framework for analyzing such representations, and work…
Non-Higgsable abelian gauge symmetry and F-theory on fiber products of rational elliptic surfaces
David R. Morrison, Daniel S. Park, Washington Taylor
We construct a general class of Calabi--Yau threefolds from fiber products of rational elliptic surfaces with section, generalizing a construction of Schoen to include all Kodaira…
Enhanced gauge symmetry in 6D F-theory models and tuned elliptic Calabi-Yau threefolds
Samuel B. Johnson, Washington Taylor
We systematically analyze the local combinations of gauge groups and matter that can arise in 6D F-theory models over a fixed base. We compare the low-energy constraints of anomaly…
Three-Index Symmetric Matter Representations of SU(2) in F-Theory from Non-Tate Form Weierstrass Models
Denis Klevers, Washington Taylor
We give an explicit construction of a class of F-theory models with matter in the three-index symmetric (4) representation of SU(2). This matter is realized at codimension two loci…
Matter in transition
Lara B. Anderson, James Gray, Nikhil Raghuram +1
We explore a novel type of transition in certain 6D and 4D quantum field theories, in which the matter content of the theory changes while the gauge group and other parts of the sp…
