Parafermions, Strings and their BRST Charges
Michael Freeman, Peter West
We show how to relate the parafermions that occur in the string to the standard construction of parafermions. This result is then used to show that one of the screening charg…
A W-String Realization of the Bosonic String
Nathan Berkovits, Mike Freeman, Peter West
It has recently been shown that the ordinary bosonic string can be represented by a special background of N=1 or N=2 strings. In this paper, it will be shown that the bosonic strin…
A Review of Strings
Peter West
Recent progress on the physical states and scattering amplitudes of the string is reviewed with particular emphasis on the relation between this string theory and the Ising m…
On the relation between integrability and infinite-dimensional algebras
M. D. Freeman, P. West
We review our work on the relation between integrability and infinite-dimensional algebras. We first consider the question of what sets of commuting charges can be constructed from…
The covariant scattering and cohomology of strings
Michael Freeman, Peter West
A general formalism for covariant string scattering is given. It is found necessary to use screening charges that are constructed from the fields including ghosts. The…
