N = 2 Superstrings with (1, 2m) Spacetime Signature

چکیده
We show that the N = 2 superstring in d = 2D ≥ 6 real dimensions, with criticality achieved by including background charges in the two real time directions, exhibits a " coordinate-freezing " phenomenon, whereby the momentum in one of the two time directions is constrained to take a specific value for each physical state. This effectively removes this time direction as a physical coordinate, leaving the theory with (1, d − 2) real spacetime signature. Norm calculations for low-lying physical states suggest that the theory is ghost free.

In this note we investigate the generalised critical N = 2 superstrings in (1, 2p) spacetime signature. We calculate the four-point functions for the tachyon operators of these theories. In contrast to the usual N = 2 superstring in (2, 2) spacetime, the four-point functions do not vanish. The exchanged particles of the four-point function are included in the physical spectrum of the correspond...
متن کاملOff-Shell Supersymmetry versus Hermiticity in Superstrings.
Superstring theory is the only known renormalizable quantum theory of gravity, and spacetime supersymmetry plays a crucial role in removing the divergences. Spacetime supersymmetry also plays a crucial role in the recent conjectures [1] of strong-weak duality in superstring theory. However, spacetime supersymmetry is only an on-shell symmetry in the conventional N 1 RamondNeveu-Schwarz (RNS) ...
متن کاملD-instantons and matter hypermultiplet
We calculate the D-instanton corrections (with all D-instanton numbers) to the quantum moduli space metric of a single matter hypermultiplet with toric isometry, in the effective N=2 supergravity arising in type-IIA superstrings compactified on a CalabiYau (CY) threefold of Hodge number h2,1 = 1. The non-perturbative quaternionic hypermultiplet metric is derived by resolution of a complex orbif...
متن کاملA hierarchy of superstrings.
We construct a hierarchy of supersymmetric string theories by showing that the general N -extended superstrings may be viewed as a special class of the (N + 1)-extended superstrings. As a side result, we nd a twisted (N + 2) superconformal algebra realized in the N -extended string. e-mail address: [email protected] e-mail address: [email protected], [email protected] Permanent a...

We discuss different aspects of the 2 + 2-signature from the point of view of the quatl theory. In particular, we compare two alternative approaches to such a spacetime signature, namely the 1+1-matrix-brane and the 2+2-target spacetime of a string.
