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). In this work, we identify O (10 11 ) F-theory QSM geometries without vector-like exotics in the representations ( 3 , 2 ) 1 / 6 , ( 3 , 1 ) − 2 / 3 and ( 1 , 1 ) 1 . The QSM geometries come in families of toric 3-folds B 3 (∆ ◦ ) obtained from triangulations of certain 3-dimensional polytopes…

Gauge symmetry breaking with fluxes and natural Standard Model structure from exceptional GUTs in F-theory

• Mathematics
• 2022
: 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 and induce chiral

This ensemble of globally consistent F-theory compactifications automatically realizes gauge coupling unification because all global consistency conditions can be reduced to a single criterion on the base of the underlying elliptically fibered Calabi-Yau fourfolds.

Reinforcement learning and genetic algorithms in the context of heterotic CalabiYau models with monad bundles are found to be highly efficient in identifying phenomenologically attractive three-family models, in cases where systematic scans are not feasible.
