Regularizing Cubic Open Neveu-Schwarz String Field Theory
نویسنده
چکیده
After introducing non-minimal variables, the midpoint insertion of Y Ȳ in cubic open Neveu-Schwarz string field theory can be replaced with an operator Nρ depending on a constant parameter ρ. As in cubic open superstring field theory using the pure spinor formalism, the operator Nρ is invertible and is equal to 1 up to a BRST-trivial quantity. So unlike the linearized equation of motion Y Ȳ QV = 0 which requires truncation of the Hilbert space in order to imply QV = 0, the linearized equationNρQV = 0 directly implies QV = 0.

Neveu - Schwarz String Field Theory
A classical action for open superstring field theory has been proposed which does not suffer from contact term problems. After generalizing this action to include the non-GSO projected states of the Neveu-Schwarz string, the pure tachyon contribution to the tachyon potential is explicitly computed. The potential has a minimum of V = −
متن کاملTachyon condensation using the disc partition function
It has been recently proposed that the background independent open superstring field theory action is given by the disc partition function with all possible open string operators inserted at the boundary of the disc. We use this proposal to study tachyon condensation in the D0-D2 system. We evaluate the disc partition function for the D0-D2 system in presence of a large Neveu-Schwarz B-field us...
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 کاملPicture Changing Operators in Closed Fermionic String Field Theory
We discuss appropriate arrangement of picture changing operators required to construct gauge invariant interaction vertices involving Neveu-Schwarz states in heterotic and closed superstring field theory. The operators required for this purpose are shown to satisfy a set of descent equations. ⋆ e-mail addresses: [email protected], [email protected] 1 A closed bosonic string field theory b...
متن کاملHeterotic String Field Theory Yuji
We construct the Neveu-Schwarz sector of heterotic string field theory using the large Hilbert space of the superghosts and the multi-string products of bosonic closed string field theory. No picture-changing operators are required as in Wess-Zumino-Witten-like open superstring field theory. The action exhibits a novel kind of nonpolynomiality: in addition to terms necessary to cover missing re...
