Open string T-duality in double space

European Physical Journal C: Particles and Fields, 2017
The role of double space is essential in the new interpretation of T-duality and consequently in an attempt to construct M-theory. The case of the open string is missing in such an approach because until now there has been no appropriate formulation of ...

Niemeier Lattices in the Free Fermionic Heterotic–String Formulation

Advances in Mathematical Physics, 2017
The spinor–vector duality was discovered in free fermionic constructions of the heterotic string in four dimensions. It played a key role in the construction of heterotic–string models with an anomaly-free extra Z′ symmetry that may remain unbroken down ...

Odderon in gauge/string duality [PDF]

Journal of High Energy Physics, 2009
At high energies, elastic hadronic cross sections, such as $pp, \overline p p, ^{\pm} p$, are dominated by vacuum exchange, which in leading order of the $1/N_c$ expansion has been identified as the BFKL Pomeron or its strong AdS dual the closed string Reggeized graviton \cite{Brower:2006ea}.

A defect in AdS3/CFT2 duality

Journal of High Energy Physics, 2022
AdS3 string theory in the stringy regime k = (R AdS /ℓ s )2 < 1 provides a laboratory for the study of holography in which both sides of AdS/CFT duality are under fairly good control.

Duality Symmetries and the Type II String Effective Action [PDF]

, 1995
We discuss the duality symmetries of Type II string effective actions in nine, ten and eleven dimensions. As a by-product we give a covariant action underlying the ten--dimensional Type IIB supergravity theory.

Baryon modes in string breaking from gauge/string duality

Physics Letters B, 2020
We consider the string breaking phenomenon within effective string models which purport to mimic QCD with two light flavors, with a special attention to baryon modes.

Strong-Weak Coupling Duality in Four Dimensional String Theory [PDF]

, 1994
We present several pieces of evidence for strong-weak coupling duality symmetry in the heterotic string theory, compactified on a six dimensional torus.

Gauge spinors and string duality [PDF]

Nuclear Physics B, 2000
When the gauge groups of the two heterotic string theories are broken, over tori, to their "SO(16)x SO(16)" subgroups, the winding modes correspond to representations which are spinorial with respect to those subgroups. Globally, the two subgroups are isomorphic neither to SO(16)x SO(16) nor to each other.

Spinor–Vector Duality and Mirror Symmetry

Universe
Mirror symmetry was first observed in worldsheet string constructions, and was shown to have profound implications in the Effective Field Theory (EFT) limit of string compactifications, and for the properties of Calabi–Yau manifolds.

Double field theory and geometric quantisation

Journal of High Energy Physics, 2021
We examine various properties of double field theory and the doubled string sigma model in the context of geometric quantisation. In particular we look at T-duality as the symplectic transformation related to an alternative choice of polarisation in the ...
