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…
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…
