1205.0120 (Zahra Rezaei)

Boundary Super-Deformations, Boundary States, and Tachyon Condensation    [PDF]

Zahra Rezaei
The open string tachyon and U(1) gauge field as longitudinal fluctuations and the velocity as transverse fluctuation of an arbitrary dimensional D-brane are considered as boundary deformations of a closed superstring free action. The path integral approach will be applied to calculate the corresponding generalized boundary states using supersymmetrized boundary actions. Obtaining the disk partition functions from the boundary states and studying the effect of tachyon condensation on both of them in the NSNS and RR sectors, leads to results that differ from the established ones.
