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 $[

Fortschritte 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.

Dimensionless Coupling of Superstrings to Supersymmetric Gauge Theories and Scale Invariant Superstring Actions [PDF]
Phys.Lett. B387 (1996) 75-79, 1996 We construct new superstring actions which are distinguished from standard superstrings by being space-time scale invariant. Like standard superstrings, they are also reparametrization invariant, space-time supersymmetric, and invariant under local scale transformations of the world sheet.

T‐Symmetry in String Geometry Theory
Advances 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 ...

Complete action for open superstring field theory [PDF]
, 2015 We construct a complete action for open superstring field theory that includes the NeveuSchwarz sector and the Ramond sector. For the Neveu-Schwarz sector, we use the string field in the large Hilbert space of the superconformal ghost sector, and the ...

Gauge invariant 1PI effective superstring field theory: inclusion of the Ramond sector [PDF]
Journal of High Energy Physics, 2015 We construct off-shell amplitudes in heterotic and type II string theories in-volving arbitrary combination of Ramond and Neveu-Schwarz sector external states.

Fortschritte der Physik, Volume 72, Issue 9-10, October 2024.Abstract In the present work, an extended description of the covariant noncommutative space is presented, which accommodates the Fuzzy Gravity model constructed previously. It is based on the historical lesson that the use of larger algebras containing all generators of the isometry of the continuous one helped in formulating a fuzzy covariant ...

Marginal Solutions for the Superstring [PDF]
JHEP 0707:050,2007, 2007 We construct a class of analytic solutions of WZW-type open superstring field theory describing marginal deformations of a reference D-brane background. The deformations we consider are generated by on-shell vertex operators with vanishing operator products.

Worldsheet formalism for decoupling limits in string theory
Journal of High Energy PhysicsWe study the bosonic sector of a decoupling limit of type IIA superstring theory, where a background Ramond-Ramond one-form is fined tuned to its critical value, such that it cancels the associated background D0-brane tension.
