Mega-Space Current Algebra and Green-Schwarz Geometry in Heterotic String Theory
Machiko Hatsuda, Shin Sasaki, Masaya Yata
We study the Lorentz and gauge connections in heterotic string theories within a framework of manifest T-duality. A central motivation is the Bergshoeff--de Roo (BdR) type parallel…
Gauss law constraint in A-theory branes
Machiko Hatsuda, Ondrej Hulık, William D. Linch +2
A-theory realizes U-duality symmetry by extending the string worldsheet to a higher dimensional brane worldvolume, in which the worldvolume and the spacetime belong to different re…
Strings and membranes from -theory five brane
Machiko Hatsuda, Ondřej Hulík, William D. Linch +3
The -theory takes U-duality symmetry as a guiding principle, with the SL(5) U-duality symmetry being described as the world-volume theory of a 5-brane. Furthermore, by…
-theory: A brane world-volume theory with manifest U-duality
Machiko Hatsuda, Ondřej Hulík, William D. Linch +3
In this paper, the -theory, an extension of F-theory, is described as a fully U-duality covariant brane theory. This theory has some distinguishing features not known fro…
Gauged Double Field Theory, Current Algebras and Heterotic Sigma Models
Machiko Hatsuda, Haruka Mori, Shin Sasaki +1
We study the generalized metric and the gauge symmetries in the gauged double field theory (DFT) in view of current algebras and sigma models. We show that the $O(D,D+n)…
Open F-branes
Machiko Hatsuda, Warren Siegel
We include in F-theory, through open Type I F-theory branes (F-branes), string theories with N = 1 supersymmetry, both Type I and heterotic. Type I branes are distinguished from Ty…
