On the Spectrum and Scattering of W_3 Strings
H. Lu, C. N. Pope, S. Schrans +1
We present a detailed investigation of scattering processes in string theory. We discover further physical states with continuous momentum, which involve excitations of the g…
The Interacting String
H. Lu, C. N. Pope, S. Schrans +1
We present a procedure for computing gauge-invariant scattering amplitudes in the string, and use it to calculate three-point and four-point functions. We show that non-vanis…
Generalised Virasoro Constructions from Affine Inonu-Wigner Contractions
Stany Schrans
We present a new method to find solutions of the Virasoro master equations for any affine Lie algebra . The basic idea is to consider first the simplified case of an I…
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…
On Sibling and Exceptional W Strings
H. Lu, C. N. Pope, S. Schrans +1
We discuss the physical spectrum for strings based on the algebras , , , and . For a simply-laced string, we find a connection with the …
The Complete Spectrum of the String
H. Lu, C. N. Pope, S. Schrans +1
We obtain the complete physical spectrum of the string, for arbitrary . The constraints freeze coordinates, while the remaining coordinates appear in the curre…
