Superstring amplitudes from BCJ numerators at one loop

Journal of High Energy Physics
We find a direct map that determines moduli-space integrands for one-loop superstring amplitudes in terms of field-theory loop integrands in the BCJ form. The latter can be computed using efficient unitarity methods, so our map provides an alternative to

Classical spectral curve of the AdS5 × S 5 lambda superstring

Journal of High Energy Physics, 2020
The classical spectral curve for the worldsheet theory of the AdS5 ×S 5 lambda superstring is constructed. The lambda string is interpreted as a regularized, non-abelian T-dual of the AdS5 ×S 5 superstring with respect to the full PSU(2, 2|4) symmetry ...

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.

Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Superstrings on AdS3 at k = 1

Journal of High Energy Physics, 2018
We study superstring theory in three dimensional Anti-de Sitter spacetime with NS-NS flux, focusing on the case where the radius of curvature is equal to the string length.

Extra dimensions in superstring theory [PDF]

Nuclear 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 $[

Analyticity and crossing symmetry of superstring loop amplitudes

Journal of High Energy Physics, 2019
Bros, Epstein and Glaser proved crossing symmetry of the S-matrix of a theory without massless fields by using certain analyticity properties of the off-shell momentum space Green’s function in the complex momentum plane.

Heterotic string solutions and coset conformal field theories

, 1993
We discuss solutions of the heterotic string theory which are analogous to bosonic and superstring backgrounds related to coset conformal field theories.

Open Superstring Field Theory on the Restricted Hilbert Space [PDF]

, 2016
Recently an action for open superstring field theory was proposed where the Neveu-Schwarz sector is formulated in the large Hilbert space while the Ramond sector lives in a restriction of the small Hilbert space.

Double Copy From Tensor Products of Metric BV■‐Algebras

Fortschritte 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.
