Vertex Operators of Open String States in the Intersecting D-brane World
arXiv:hep-ph/0209099
Abstract
Starting with a new bosonization scheme for the βγCFT of the super-conformal ghosts, vertex operators are constructed for massless open string states in the intersecting D-brane world. These vertex operators satisfy all requirements for a consistent RNS formulation of superstring theories, so GSO projections can be properly taken.
