Taming the supergravity description of non - BPS D - branes : the D / D̄ solution
We obtain the supergravity solution which describes a bound state of D-string/anti-D-string pairs attached to different fixed planes of an orbifold, in type IIB string theory compactified on T /Z2. For parameters at which the conformal field theory point of view predicts stability, the solution displays a repulson-like singularity. However, we observe that a D-string/anti-D-string pair probe in...
متن کاملSupergravity Description of Non-BPS Branes
We construct supergravity solutions that correspond to N Dp-branes coinciding with N Dp-branes. We study the physical properties of the solutions and analyse the supergravity description of tachyon condensation. We construct an interpolation between the brane-antibrane solution and the Schwarzschild solution and discuss its possible application to the study of non-supersymmetric black holes. Ma...
متن کاملStacking non-BPS D-Branes
We present a candidate supergravity solution for a stacked configuration of stable non-BPS D-branes in Type II string theory compactified on T /Z2. This gives a supergravity description of nonabelian tachyon condensation on the brane worldvolume. BROWN-HET-1263 IC/2001/27
متن کاملStable Non - Bps D - Branes and Their Classical Description
We review how to describe the stable non-BPS D-branes of type II string theory from a classical perspective, and discuss the properties of the space-time geometry associated to these configurations. This is relevant in order to see whether and how the gauge/gravity correspondence can be formulated in non-conformal and non-supersymmetric settings.
متن کاملAnomalous Couplings of Non-bps D-branes
Non-BPS type II D-branes couple to R-R potentials via an action that, upon tachyon condensation, gives rise to the Wess-Zumino action of BPS D-branes. Non-BPS branes in string theory have received a lot of attention after the seminal work by Sen [1], as such non-BPS states allow for highly non-trivial tests of string dualities. In a related development, unstable and/or non-BPS D-branes have pla...
