Massless Boundary Sine-Gordon Model Coupled to External Fields
H. Kogetsu, S. Teraguchi
We investigate a generalization of the massless boundary sine-Gordon model with conformal invariance, which has been used to describe an array of D-branes (or rolling tachyon). We…

Gauge Structure of Vacuum String Field Theory
H. Hata, H. Kogetsu, S. Teraguchi
We study the gauge structure of vacuum string field theory expanded around the D-brane solution, namely, the gauge transformation and the transversality condition of the massless v…
