Gauge symmetry in background charge conformal field theory

Gauge Symmetry in Background Charge Conformal Field Theory *

We present a mechanism to construct four-dimensional charged massless Ramond states using the discrete states of a fivebrane Liouville internal conformal field theory. This conformal field theory has background charge, and admits an inner product which allows positive norm states. A connection among supergravity soliton solutions, Liouville conformal field theory, non-critical string theory and...

Yangian symmetry in conformal field theory

We show that the SU(N), level-1 Wess-Zumino-Witten conformal field theory provides a natural realization of the Yangian Y(sl~) for N _> 3. We also construct a hamiltonian/-/2 which commutes with the Yangian generators and study its spectrum. Our results, which generalize work by Haldane et al. [ 1 ], provide the field theory extension of the algebraic structure of the SU(N) Haldane-Shastry spin...

Yangian Symmetry in Conformal Field Theory

We show that the SU(N), level-1 Wess-Zumino-Witten conformal field theory provides a natural realization of the Yangian Y (slN) for N ≥ 3. We also construct a hamiltonian H2 which commutes with the Yangian generators and study its spectrum. Our results, which generalize work by Haldane et al. [1], provide the field theory extension of the algebraic structure of the SU(N) Haldane-Shastry spin ch...
