Toward Open-Closed String Theoretical Description of Rolling Tachyon
Kazuki Ohmori
We consider how the time-dependent decay process of an unstable D-brane should be described in the full (quantum) open-closed string theory. It is argued that the system, starting…
Level-Expansion Analysis in NS Superstring Field Theory Revisited
Kazuki Ohmori
We study the level-expansion structure of the NS string field theory actions, mainly focusing on the modified (i.e. 0-picture in the NS sector) cubic superstring field theory. This…
On Ghost Structure of Vacuum Superstring Field Theory
Kazuki Ohmori
After discussing the general form of the kinetic operator around the tachyon vacuum, we determine the specific form of the pure-ghost kinetic operator Q^ by requiring the twist inv…
Comments on Solutions of Vacuum Superstring Field Theory
Kazuki Ohmori
We study classical solutions of vacuum version of Berkovits' superstring field theory, focusing on the (super)ghost sector. We first argue that the supersliver state which is annih…
CFT Description of Identity String Field: Toward Derivation of the VSFT Action
Isao Kishimoto, Kazuki Ohmori
We concretely define the identity string field as a surface state and deal with it consistently in terms of conformal field theory language, never using its formal properties nor o…
Survey of the Tachyonic Lump in Bosonic String Field Theory
Kazuki Ohmori
We study some properties of the tachyonic lumps in the level truncation scheme of bosonic cubic string field theory. We find that several gauges work well and that the size of the…
