6D Heterotic Little String Theories and F-theory Geometry: An Introduction
Michele Del Zotto, Muyang Liu, Paul-Konstantin Oehlmann
We review here some aspects of our recent works about the geometric engineering of heterotic little string theories using F-theory. Building on the seminal work by Aspinwall and Mo…
Back to Heterotic Strings on ALE Spaces: Part II -- Geometry of T-dual Little Strings
Michele Del Zotto, Muyang Liu, Paul-Konstantin Oehlmann
This work is the second of a series of papers devoted to revisiting the properties of Heterotic string compactifications on ALE spaces. In this project we study the geometric count…
Back to Heterotic Strings on ALE Spaces: Part I -- Instantons, 2-groups and T-duality
Michele Del Zotto, Muyang Liu, Paul-Konstantin Oehlmann
In this paper we begin revisiting the little string theories (LSTs) which govern the dynamics of the instantonic heterotic five-branes probing ALE singularities, b…
Statistics of Limit Root Bundles Relevant for Exact Matter Spectra of F-Theory MSSMs
Martin Bies, Mirjam Cvetič, Muyang Liu
In the largest, currently known, class of one Quadrillion globally consistent F-theory Standard Models with gauge coupling unification and no chiral exotics, the vector-like spectr…
Root Bundles and Towards Exact Matter Spectra of F-theory MSSMs
Martin Bies, Mirjam Cvetič, Ron Donagi +2
Motivated by the appearance of fractional powers of line bundles in studies of vector-like spectra in 4d F-theory compactifications, we analyze the structure and origin of these bu…
Machine Learning and Algebraic Approaches towards Complete Matter Spectra in 4d F-theory
Martin Bies, Mirjam Cvetic, Ron Donagi +3
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 b…
Yukawa Hierarchies in Global F-theory Models
Mirjam Cvetic, Ling Lin, Muyang Liu +2
We argue that global F-theory compactifications to four dimensions generally exhibit higher rank Yukawa matrices from multiple geometric contributions known as Yukawa points. The h…
A Quadrillion Standard Models from F-theory
Mirjam Cvetic, James Halverson, Ling Lin +2
We present an explicit construction of globally consistent string compactifications that realize the exact chiral spectrum of the Standard Model of particle phy…
An F-theory Realization of the Chiral MSSM with -Parity
Mirjam Cvetič, Ling Lin, Muyang Liu +1
Using F-theory we construct 4D SUGRA theories with the Standard Model gauge group, three chiral generations, and matter parity in order to forbid all dimension four ba…
No-go for tree-level R-symmetry breaking
Feihu Liu, Muyang Liu, Zheng Sun
We show that in gauge mediation models with tree-level R-symmetry breaking where supersymmetry and R-symmetries are broken by different fields, the gaugino mass either vanishes at…
