D-branes in Melvin Background
Tadashi Takayanagi, Tadaoki Uesugi
In this paper we discuss D-branes in the Melvin background and its supersymmetric generalizations. In particular we determine the D-brane spectra in these backgrounds by constructi…
Orbifolds as Melvin Geometry
Tadashi Takayanagi, Tadaoki Uesugi
In this paper we explicitly show that the various noncompact abelian orbifolds are realized as special limits of parameters in type II (NSNS) Melvin background and its higher dimen…
On the Supersymmetry of Non-BPS D-brane
Seiji Terashima, Tadaoki Uesugi
In this paper we extend the boundary string field theory action for a non-BPS D-brane to the one including the target space fermions and the nonlinear supersymmetry with 32 superch…
Brane-Antibrane Action from Boundary String Field Theory
Tadashi Takayanagi, Seiji Terashima, Tadaoki Uesugi
In this paper we give the boundary string field theory description of brane-antibrane systems. From the world-sheet action of brane-antibrane systems we obtain the tachyon potentia…
