Journal of High Energy Physics, 2021 We consider, at the linearized level, the superspace formulation of lower-dimensional F-theory. In particular, we describe the embedding of 3D Type II super-gravity of the superstring, or 4D, N = 1 supergravity of M-theory, into the corresponding F ...

F-theory with worldvolume sectioning [PDF]
Journal of High Energy Physics, 2021 We describe the worldvolume for the bosonic sector of the lower-dimensional F-theory that embeds 5D, N=1 M-theory and the 4D type II superstring. This theory is a complexification of the fundamental 5-brane theory that embeds the 4D, N=1 M-theory of the ...

Physics Letters B, 2014 We study the dynamics of axion-like fields in F-theory and suggest that they can serve as inflatons in models of natural inflation. The axions arise from harmonic three-forms on the F-theory compactification space and parameterize a complex torus that ...

Towards bootstrapping F-theory
Journal of High Energy PhysicsWe consider type IIB string theory with N D3 branes and various configurations of sevenbranes, such that the string coupling g s is fixed to a constant finite value.

On the frozen F-theory landscape
Journal of High Energy PhysicsWe study 6d $$\mathcal{N}$$ = (1, 0) supergravity theories arising in the frozen phase of F-theory. For each of the known global models, we construct an F-theory compactification in the unfrozen phase with an identical non-abelian gauge algebra and ...

Journal of High Energy Physics, 2005 We consider the construction of a topological version of F-theory on a particular Spin(7) 8-manifold which is a Calabi-Yau 3-fold times a 2-torus. We write an action for this theory in eight dimensions and reduce it to lower dimensions using Hitchin's

Algebraic description of G-flux in F-theory: new techniques for F-theory phenomenology [PDF]
Fortschritte der Physik, 2012 We give a global algebraic description of the four-form flux in F-theory. We present how to compute its D3-tadpole and how to calculate the number of four-dimensional chiral states at the intersection of 7-branes directly in F-theory.

Classification of Spot-Welded Joints in Laser Thermography Data Using Convolutional Neural Networks
IEEE Access, 2021 Spot welding is a crucial process step in various industries. However, classification of spot welding quality is still a tedious process due to the complexity and sensitivity of the test material, which drain conventional approaches to its limits.
