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,

• Rolling Tachyon (2002, background): “Nevertheless one might expect that there are non-Fock space excitations of open string field configuration describing closed string excitations[8, 9, 10, 11], and that the decay process transfers the energy of the original brane to these closed string excitations.”
• Comments on Schnabl's analytic solution for tachyon condensation in Witten's open string field theory (2006, background): “Another example is the twisted butterfly state [19, 20, 21] in vacuum string field theory [22, 23, 24].”
• A simple analytic solution for tachyon condensation (2009, background): “Since our solution describes an empty vacuum without D-branes, the field configuration should leave the closed string background undisturbed.”

• Proof of vanishing cohomology at the tachyon vacuum (2006, background): “Since VSFT is thought to be a singular limit of ordinary OSFT, in which the BRST operator becomes a c-ghost operator inserted at the midpoint [34], it would be interesting to see whether  becomes a simple operator formed out of just the b-ghost in this limit.”
• Closed strings as imaginary D-branes (2003, methodology): “Thus we recover precisely the scenario of [23].”
