New Coherent String States and Minimal Uncertainty in WZWN Models

We study the properties of exact (all level k) quantum coherent states in the context of string theory on a group manifold (WZWN models). Coherent states of WZWN models may help to solve the unitarity problem: Having positive norm, they consistently describe the very massive string states (otherwise excluded by the spin-level condition). These states can be… CONTINUE READING
