Ghost Kinetic Operator of Vacuum String Field Theory

High Energy Physics - Theory 2009-11-07 v2

Abstract

Using the data of eigenvalues and eigenvectors of Neumann matrices in the 3-string vertex, we prove analytically that the ghost kinetic operator of vacuum string field theory obtained by Hata and Kawano is equal to the ghost operator inserted at the open string midpoint. We also comment on the values of determinants appearing in the norm of sliver state.
