Quadrillion F-Theory Compactifications with the Exact Chiral Spectrum of the Standard Model. [PDF]
We present O(10^{15}) string compactifications with the exact chiral spectrum of the standard model of particle physics. This ensemble of globally consistent F-theory compactifications automatically realizes gauge coupling unification.

Perturbative moduli stabilisation in type IIB/F-theory framework [PDF]
We propose a new mechanism of (geometric) moduli stabilisation in type IIB/F-theory four-dimensional compactifications on Calabi–Yau manifolds, in the presence of 7-branes, that does not rely on non-perturbative effects.

Discrete gauge groups in certain F-theory models in six dimensions [PDF]
A bstractWe construct six-dimensional (6D) F-theory models in which discrete ℤ5, ℤ4, ℤ3, and ℤ2 gauge symmetries arise. We demonstrate that a special family of “Fano 3-folds” is a useful tool for constructing the aforementioned models.

F-theory vacua and α′-corrections
In this work we analyze F-theory and Type IIB orientifold compactifications to study α′-corrections to the four-dimensional, N $$ \mathcal{N} $$ = 1 effective actions.

F-theory on quotients of elliptic Calabi-Yau threefolds [PDF]
In this work we consider quotients of elliptically fibered Calabi-Yau threefolds by freely acting discrete groups and the associated physics of F-theory compactifications on such backgrounds.

F-theory uplifts and GUTs [PDF]
We study the F-theory uplift of Type IIB orientifold models on compact Calabi-Yau threefolds containing divisors which are del Pezzo surfaces. We consider two examples defined via del Pezzo transitions of the quintic. The first model has an orientifold projection leading to two disjoint O7-planes and the second involution acts via an exchange of two ...

F-theory on quotient threefolds with (2,0) discrete superconformal matter [PDF]
A bstractWe explore 6-dimensional compactifications of F-theory exhibiting (2, 0) superconformal theories coupled to gravity that include discretely charged superconformal matter.

F-theory from fundamental five-branes
We describe the worldvolume for the bosonic sector of the lower-dimensional F-theory that embeds 4D, N=1 M-theory and the 3D Type II superstring. The worldvolume (5-brane) theory is that of a single 6D gauge 2-form X MN (σ P ) whose field strength is ...

Covariant formulation of f(Q) theory
In Symmetric Teleparallel General Relativity, gravity is attributed to the non-metricity. The so-called “coincident gauge” is usually taken in this theory so that the affine connection vanishes and the metric is the only fundamental variable.
