Covariant formulation of f(Q) theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
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.

F-theory with quantized fluxes [PDF]

open access: yesAdvances in Theoretical and Mathematical Physics, 1999
We present evidence that the CHL string in eight dimensions is dual to F-theory compactified on an elliptic K3 with a $Γ_{0}(2)$ monodromy group. The monodromy group $Γ_{0}(2)$ allows one to turn on the flux of an antisymmetric two form along the base. The $B_{μν}$ flux is quantized and therefore the moduli space of the CHL string is disconnected from ...

Sparks as radioemitters

open access: yesComptes Rendus. Physique, 2020
In the early experiments on radiocommunication, Hertz, Branly, Lodge, Marconi used as emitter a spark produced by a high electric tension. Why did this spark emit an electromagnetic radiation?

Three-form periods on Calabi-Yau fourfolds: Toric hypersurfaces and F-theory applications [PDF]

open access: yes, 2017
The study of the geometry of Calabi-Yau fourfolds is relevant for compactifications of string theory, M-theory, and F-theory to various dimensions. This work introduces the mathematical machinery to derive the complete moduli dependence of the periods of

F‐theory and Dark Energy

open access: yesFortschritte der Physik, 2019
AbstractMotivated by its potential use as a starting point for solving various cosmological constant problems, we study F‐theory compactified on the warped product where Y8 is a manifold, and the S3 factor is the target space of an Wess–Zumino–Witten (WZW) model at level N.

The footprint of F-theory at the LHC [PDF]

open access: yesJournal of High Energy Physics, 2009
Recent work has shown that compactifications of F-theory provide a potentially attractive phenomenological scenario. The low energy characteristics of F-theory GUTs consist of a deformation away from a minimal gauge mediation scenario with a high messenger scale. The soft scalar masses of the theory are all shifted by a stringy effect which survives to

Chiral anomalies on a circle and their cancellation in F-theory [PDF]

open access: yes, 2017
We study in detail how four-dimensional local anomalies manifest themselves when the theory is compactified on a circle. By integrating out the Kaluza-Klein modes in a way that preserves the four-dimensional symmetries in the UV, we show that the three ...
