Fundamental superstrings as holograms [PDF]
The worldsheet of a macroscopic fundamental superstring in the Green-Schwarz light-cone gauge is viewed as a possible boundary hologram of the near horizon region of a small black string.

M-Theory (the Theory Formerly Known as Strings) [PDF]
Superunification underwent a major paradigm shift in 1984 when eleven-dimensional supergravity was knocked off its pedestal by ten-dimensional superstrings.

Non-perturbative triality in heterotic and type II N=2 strings [PDF]
The non-perturbative equivalence of four-dimensional N = 2 superstrings with three vector multiplets and four hypermultiplets is analysed. These models are obtained through freely acting orbifold compactifications from the heterotic, the symmetric and ...

Connecting the ambitwistor and the sectorized heterotic strings
The sectorized description of the (chiral) heterotic string using pure spinors has been misleadingly viewed as an infinite tension string. One evidence for this fact comes from the tree level 3-point graviton amplitude, which we show to contain the usual

String (Gravi)photons, “Dark Brane Photons”, Holography and the Hypercharge Portal
Abstract The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly‐coupled string theory. Both the direct mixing as well as effective terms that provide mixing after inclusion of SM corrections are estimated to lowest order.

Superstring Backgrounds in String Geometry
String geometry theory is a candidate of the nonperturbative formulation of string theory. In order to determine the string vacuum, we need to clarify how superstring backgrounds are described in string geometry theory. In this paper, we show that all the type IIA, IIB, SO(32) type I, and SO(32) and E8 × E8 heterotic superstring backgrounds are ...

Normal form of nilpotent vector field near the tip of the pure spinor cone
Pure spinor formalism implies that supergravity equations in space-time are equivalent to the requirement that the worldsheet sigma-model satisfies certain properties.

Boundary conditions and heterotic construction in topological membrane theory [PDF]
Using the topological membrane approach to string theory, we suggest a geometric origin for the heterotic string. We show how different membrane boundary conditions lead to different string theories. We discuss the construction of closed oriented strings

Manifest spacetime supersymmetry and the superstring
The algebra of spacetime supersymmetry generators in the RNS formalism for the superstring closes only up to a picture-changing operation. After adding non-minimal variables and working in the “large” Hilbert space, the algebra closes without picture ...
