Superstring partition functions in the doubled formalism
Computation of superstring partition functions for the non-linear sigma model on the product of a two-torus and its dual within the scope of the doubled formalism is presented. We verify that it reproduces the partition functions of the toroidally compactified type–IIA and type–IIB theories for appropriate choices of the GSO projection.
متن کاملDiscretized superstring in three-dimensional superspace.
The partition function of the discretized superstring in a target superspace of three (Euclidean) bosonic dimensions, is shown, for a fixed triangulation of the random world sheet, to be derived from the partition function of a discretized bosonic string with an external field present in the action in the form of a specific constant matrix, using first order forms of the actions. This latter pa...
متن کاملSuperembedding approach to superstring in AdS 5 × S 5 superspace
We review the spinor moving frame formulations and generalized action principle for super-p-branes, describe in detail the superembedding approach to superstring in general type IIB supergravity background and present the complete superembedding description of type IIB superstring in the AdS5 × S 5 superspace. This contribution is devoted to the memory of Wolfgang Kummer who untimely left us in...
متن کاملMassive Superstring Vertex Operator in D = 10 Superspace Nathan Berkovits
Using the pure spinor formalism for the superstring, the vertex operator for the first massive states of the open superstring is constructed in a manifestly super-Poincaré co-variant manner. This vertex operator describes a massive spin-two multiplet in terms of ten-dimensional superfields.
