F- Theory GUT's [PDF]

open access: yesProceedings of Proceedings of the Corfu Summer Institute 2014 — PoS(CORFU2014), 2015
In this lecture, an overview of current F-theory model building techniques is presented. In F-theory GUT symmetries are associated to the singularities of the elliptically fibred internal (compact) space. Models with gauge groups emerging as subgroups of the exceptional group E8 are presented. Moreover, GUTs with abelian and discrete symmetries arising

F-theory amplitudes

open access: yes, 2020
We propose 4-point S-matrices for three-dimensional F-theory. We will use the twistor formalism to facilitate constructing the amplitude. We write the amplitude in a way such that the F-symmetry (U-duality symmetry) is manifest. The amplitude can be schematically written as $A_{4} = w^{4}/stu$, where $w$ is an analog of the linearized Weyl tensor in F ...

Flavor hierarchy from F-theory [PDF]

open access: yesNuclear Physics B, 2010
It has recently been shown that F-theory based constructions provide a potentially promising avenue for engineering GUT models which descend to the MSSM. In this note we show that in the presence of background fluxes, these models automatically achieve hierarchical Yukawa matrices in the quark and lepton sectors.

M/F-theory as Mf-theory

open access: yesReviews in Mathematical Physics, 2023
In the quest for mathematical foundations of M-theory, the Hypothesis H that fluxes are quantized in Cohomotopy theory, implies, on flat but possibly singular spacetimes, that M-brane charges locally organize into equivariant homotopy groups of spheres.

G 4 flux, algebraic cycles and complex structure moduli stabilization

open access: yesJournal of High Energy Physics, 2021
We construct G 4 fluxes that stabilize all of the 426 complex structure moduli of the sextic Calabi-Yau fourfold at the Fermat point. Studying flux stabilization usually requires solving Picard-Fuchs equations, which becomes unfeasible for models with ...

PARALLELED CHARACTERS IN THE DRAMATIC WORKS OF HORTENSIA PAPADAT-BENGESCU [PDF]

open access: yesDiversitate si Identitate Culturala in Europa, 2015
This article proposes a psychoanalytical approach to two paralleled literary characters whom Hortensia Papadat-Bengescu places into opposition in order to introduce her readers to feminine hypostases of wish fulfilment.
