Extra dimensions in superstring theory [PDF]

open access: yesNuclear Physics B, 1997
It was earlier shown that an SO(9,1) $ ^\a$ spinor variable can be constructed from RNS matter and ghost fields. $ ^\a$ has a bosonic worldsheet super-partner $ ^\a$ which plays the role of a twistor variable, satisfying $ ^ = \partial x^ +i ^ \partial $. For Type IIA superstrings, the left-moving $[ _L^\a, _L^\a]$ and right-moving $[

Double Copy From Tensor Products of Metric BV■‐Algebras

open access: yesFortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

Dual D-brane actions in nonrelativistic string theory

open access: yesJournal of High Energy Physics, 2022
We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string theory.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

open access: yesFortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Equivalence of two contour prescriptions in superstring perturbation theory

open access: yesJournal of High Energy Physics, 2017
Conventional superstring perturbation theory based on the world-sheet approach gives divergent results for the S-matrix whenever the total center of mass energy of the incoming particles exceeds the threshold of production of any final state consistent ...

T‐Symmetry in String Geometry Theory

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

SUPERCONFORMAL GAUGE THEORIES AND NONCRITICAL SUPERSTRINGS [PDF]

open access: yesInternational Journal of Modern Physics A, 2004
We consider effective actions for six-dimensional noncritical superstrings. We show that the addition of N units of RR flux and of Nf space–time filling D5-branes produces AdS 5×S1 solutions with curvature comparable to the string scale. These solutions have the right structure to be dual to [Formula: see text] supersymmetric SU (N) gauge theories ...

Quantum spectral curve for the η-deformed AdS5×S5 superstring

open access: yesNuclear Physics B, 2017
The spectral problem for the AdS5×S5 superstring and its dual planar maximally supersymmetric Yang–Mills theory can be efficiently solved through a set of functional equations known as the quantum spectral curve. We discuss how the same concepts apply
