F-theory is perhaps the most general currently available approach to study non-perturbative
string compactifications in their geometric, large radius regime. It opens up a wide and ever …

In F-theory compactifications, the abelian gauge sector is encoded in global structures of the
internal geometry. These structures lie at the intersection of algebraic and arithmetic …

A bstract We show that F-theory compactifications with abelian gauge factors generally
exhibit a non-trivial global gauge group structure. The geometric origin of this structure lies …

A bstract We study elliptic fibrations for F-theory compactifications realizing 4d and 6d
supersymmetric gauge theories with abelian gauge factors. In the fibration these U (1) …

string compactifications in their geometric, large radius regime. It opens up a wide and ever …

A bstract F-theory compactified on singular, elliptically fibered Calabi-Yau five-folds gives
rise to two-dimensional gauge theories preserving N=(0, 2) supersymmetry. In this paper we …

We study the realization of axion inflation models in the complex structure moduli spaces of
Calabi–Yau threefolds and fourfolds. The axions arise close to special points of these …

A bstract We study the manifestation of local gauge anomalies of four-and six-dimensional
field theories in the lower-dimensional Kaluza-Klein theory obtained after circle …

A bstract We explore novel gauge enhancements from abelian to non-simply-connected
gauge groups in F-theory. To this end we consider complex structure deformations of elliptic …

The recent excess in diphoton events around 750 GeV seen by the ATLAS and CMS
experiments could be hinting at the existence of new vector-like charged matter around the …
