The Low-level Spectrum of the String
H. Lu, B. E. W. Nilsson, C. N. Pope +2
We investigate the spectrum of physical states in the string theory, up to level 2 for a multi-scalar string, and up to level 4 for the two-scalar string. The (open) st…
A Note on N=2 Superstrings
J. R. Bienkowska, H. Lu
In this note we investigate the generalised critical superstrings in spacetime signature. We calculate the four-point functions for the tachyon operators of these th…
On Realisations of W Algebras
H. Lu, C. N. Pope
It has been known for some time that algebras can be realised in terms of an energy-momentum tensor together with additional free scalar fields. Some recent results have shown…
New Realisations of W Algebras and W Strings
H. Lu, C. N. Pope, S. Schrans +1
We discuss new realisations of algebras in which the currents are expressed in terms of two arbitrary commuting energy-momentum tensors together with a set of free scalar field…
