Complete action for open superstring field theory with cyclic A∞ structure [PDF]
, 2016 A bstractWe construct a gauge invariant action for the Neveu-Schwarz and Ramond sectors of open superstring field theory realizing a cyclic A∞ structure, providing the first complete and fully explicit solution to the classical Batalin-Vilkovisky master ...

Open superstring field theory on the restricted Hilbert space [PDF]
, 2016 A bstractIt appears that the formulation of an action for the Ramond sector of open superstring field theory requires to either restrict the Hilbert space for the Ramond sector or to introduce auxiliary fields with picture −3/2.

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.

Fermion masses in superstring theory [PDF]
Nuclear Physics B - Proceedings Supplements, 1995 We give a model-independent discussion of fermion masses in four-dimensional heterotic superstring theories. We discuss the tree level contributions and quantum corrections, including one-loop threshold effects and masses generated as a result of non-perturbative supersymmetry breaking. We also point out that superstring models give rise to a generic $

Exotic origins of tensionless superstrings
Physics Letters B, 2020 A new type of tensionless superstring theory, called the Inhomogeneous tensionless superstring, has been recently introduced. This is characterised by a residual symmetry algebra on the worldsheet richer in structure than the previously known symmetry ...

Factorization and unitarity in superstring theory [PDF]
Journal of High Energy Physics, 2005 The overall coefficient of the two-loop 4-particle amplitude in superstring theory is determined by making use of the factorization and unitarity. To accomplish this we computed in detail all the relevant tree and one-loop amplitudes involved and determined their overall coefficients in a consistent way.

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 ...

Off-shell Supersymmetry versus Hermiticity in the Superstring [PDF]
Phys.Rev.Lett. 77 (1996) 2891-2892, 1996 We point out that off-shell four-dimensional supersymmetry implies strange hermiticity properties for the N=1 RNS superstring. However, these hermiticity properties become natural when the N=1 superstring is embedded into an N=2 superstring.

Open superstring field theory based on the supermoduli space [PDF]
, 2017 A bstractWe present a new approach to formulating open superstring field theory based on the covering of the supermoduli space of super-Riemann surfaces and explicitly construct a gauge-invariant action in the Neveu-Schwarz sector up to quartic ...
