Vacuum String Field Theory
, 2001
"... This is a brief review of vacuum string field theory, a new approach to open string field theory based on the stable vacuum of the tachyon. We discuss the sliver state explaining its role as a projector in the space of halfstring functionals. We review the construction of Dbrane solutions in vacuu ..."

Siegel Gauge in Vacuum String Field Theory
"... We study the star algebra of ghost sector in vacuum string field theory (VSFT). We show that the star product of two states in the Siegel gauge is BRST exact if we take the BRST charge to be the one found in [1], and the BRST exact states are nil factors in the star algebra. By introducing a new sta ..."

, 2002
"... We reveal a novel mathematical structure in physical observables, the mass of tachyon fluctuation mode and the energy density, associated with a classical solution of vacuum string field theory constructed previously [hepth/0108150]. We find that they are expressed in terms of quantities which appa ..."

Ghost Structure and Closed Strings in Vacuum String Field Theory
, 2003
"... We complete the construction of vacuum string field theory by proposing a canonical choice of ghost kinetic term – a local insertion of the ghost field at the string midpoint with an infinite normalization. This choice, supported by level expansion studies in the Siegel gauge, eprint archive: ..."

The Equality of Solutions in Vacuum String Field Theory,” arXiv:hepth/0201149
"... We analytically prove that the matter solution of vacuum string field theory constructed by Kostelecky and Potting is the matter sliver state. We also give an analytical proof that the ghost solution by Hata and Kawano is the sliver state in the twisted ghost CFT. It is also proved that the candidat ..."
