Nonlinear Supersymmetry Without the GSO Projection and Unstable D9-Brane
Orientable open string theories containing both bosons and fermions without the GSO projection are expected to have the 10 dimensional N = 2(A) space-time supersymmetry in a spontaneously broken phase. We study the low-energy theorem for the nonlinearly realized N = 2 supersymmetry using the effective action for an unstable D9-brane. It is explicitly confirmed that the 4-fermion open string amp...
متن کاملSpontaneously Broken Space-Time Supersymmetry in Open String Theory without GSO Projection
We argue that orientable open string theory without GSO projection has N=2 spacetime supersymmetry in a spontaneously broken phase. The arguments are presented both in Neveu-Schwarz-Ramond and Green-Schwarz formulations. The formal but explicit supersymmetry transformation law for string field is given in the framework of Witten’s open string field theory. Our results support a fundamental assu...
متن کاملThe Super D9-Brane and its Truncations
We consider two inequivalent truncations of the super D9–brane: the “Heterotic” and the “Type I” truncation. Both of them lead to an N = 1 nonlinear supersymmetrization of the D = 10 cosmological constant. The propagating degrees of freedom in the Heterotic and Type I truncation are given by the components of a D = 10 vector multiplet and a single Majorana-Weyl spinor, respectively. As a by-pro...
متن کاملSupersymmetric Born-Infeld from the D9-brane
Using the superembedding approach, the full supersymmetric effective field theory of the D9-brane, super Born-Infeld theory, is fixed by the so called F-constraint. The odd-odd components of the theory’s super field strength, fαβ, are implied by this constraint. Given fαβ, the super Bianchi identities imply the theory’s equations of motion. We calculate fαβ up to order 5 in fields, correspondin...
متن کاملChiral rings and GSO projection in Orbifolds
The GSO projection in the twisted sector of orbifold background is sometimes subtle and incompatible descriptions are found in literatures. Here, from the equivalence of partition functions in NSR and GS formalisms, we give a simple rule of GSO projection for the chiral rings of string theory in C/Zn, r = 1, 2, 3. Necessary constructions of chiral rings are given by explicit mode analysis. ∗Wor...
