Mixmaster Horava-Witten Cosmology [PDF]

, 2001
We discuss various superstring effective actions and, in particular, their common sector which leads to the so-called pre-big-bang cosmology (cosmology in a weak coupling limit of heterotic superstring).

Notes on the Wess-Zumino-Witten-like structure: L ∞ triplet and NS-NS superstring field theory

Journal of High Energy Physics, 2017
In the NS-NS sector of superstring field theory, there potentially exist three nilpotent generators of gauge transformations and two constraint equations: it makes the gauge algebra of type II theory somewhat complicated.

Superstring Dualities [PDF]

, 1995
This talk is divided into two parts. The first part reviews some of the duality relationships between superstring theories. These relationships are interpreted as providing evidence for the existence of a unique underlying fundamental theory.

Superstring Backgrounds in String Geometry

Advances in High Energy Physics, 2021
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.

``Alternative $N=(4,0)$ Superstring and $\s$-Models''

, 1994
We present an alternative $N=(4,0)$ superstring theory, with field content different from that of previously-known $N=(4,0)$ superstring theories. This theory is presented as a non-linear $\s$-model on the coset $SU(n,1) / SU(n) \otimes U(1)$ as the ...

N=2 Heterotic Superstring and its Dual Theory in Five Dimensions [PDF]

, 1995
We study quantum effects in five dimensions in heterotic superstring theory compactified on K_3 x S_1 and analyze the conjecture that its dual effective theory is eleven-dimensional supergravity compactified on a Calabi-Yau threefold. This theory is also

Gravitational scattering of massless scalars in QFT and superstring theory [PDF]

, 2005
In this paper we perform the calculation of the gravitational scattering amplitude for 4 massless scalars in quantum field theory and Type II superstring theory.

Conformal Relativity versus Brans–Dicke and Superstring Theories

Entropy, 2012
We show how conformal relativity is related to Brans–Dicke theory and to low-energy-effective superstring theory. Conformal relativity or the Hoyle–Narlikar theory is invariant with respect to conformal transformations of the metric.

Dilatonic black holes in superstring gravity [PDF]

, 2019
We solve the dilaton field equation in the background of a spherically symmetric black hole in type II superstring theory with $\alpha'^3$ corrections in arbitrary $d$ spacetime dimensions.
