The no - ghost theorem in curved backgrounds with a timelike u ( 1 ) : NSR string
نویسنده
چکیده
It is well-known that the standard no-ghost theorem is valid as long as the background has the light-cone directions. We prove the noghost theorem for the NSR string when only the timelike direction is flat. This is done by the BRST quantization, using the technique of Frenkel, Garland and Zuckerman and our previous results for the bosonic string. The theorem actually applies as long as the timelike direction is written as a u(1) SCFT. PACS codes: 11.25.-w, 11.25.Hf

The no-ghost theorem for string theory in curved backgrounds with a flat timelike direction
It is well-known that the standard no-ghost theorem can be extended to the general c = 26 CFT with d-dimensional Minkowski spacetime M(1,d−1) and a compact unitary CFT K of central charge cK = 26 − d. The theorem has been established under the assumption d ≥ 2 so far. We prove the no-ghost theorem for d = 1, i.e., when only the timelike direction is flat. This is done using the technique of Fre...
متن کاملSupersymmetric string vacua on AdS3 ×N
String backgrounds of the form AdS 3 × N that give rise to two dimensional spacetime superconformal symmetry are constructed. 1. Introduction In this letter we study the conditions on curved string backgrounds of the form AdS 3 × N that give rise to spacetime superconformal symmetry. We use the NSR formulation; for simplicity we describe the left moving sector only – it can be combined with the...
متن کاملGhost-matter Mixing and Feigenbaum Universality in String Theory
Brane-like vertex operators, defining backgrounds with the ghost-matter mixing in NSR superstring theory, play an important role in a world-sheet formulation of D-branes and M theory, being creation operators for extended objects in the second quantized formalism. In this paper we show that dilaton’s beta function in ghost-matter mixing backgrounds becomes stochastic. The renormalization group ...
متن کاملThe String Measure and Spectral Flow of Critical N = 2 Strings
The general structure of N=2 moduli space at arbitrary genus and instanton number is investigated. The N=2 NSR string measure is calculated, yielding picture-and U(1) ghost number-changing operator insertions. An explicit formula for the spectral flow operator acting on vertex operators is given, and its effect on N=2 string amplitudes is discussed.
متن کاملGhost Tachyon Condensation, Brane-like States and Extra Time Dimension
NSR superstring theory contains a tower of physical vertex operators (brane-like states) which exist at non-zero pictures only, i.e. are essentially mixed with superconformal ghosts. Some of these states are massless, they are responsible for creating D-branes. Other states are tachyonic (called ghost tachyons) creating a problem for the vacuum stability of the NSR model. In this paper we explo...
