So(32) Spinors of Type I and Other Solitons on Brane-antibrane Pair
نویسنده
چکیده
We construct the SO(32) spinor state in weakly coupled type I string theory as a kink solution of the tachyon field on the D-string − anti-D-string pair and calculate its mass. We also give a description of this system in terms of an exact boundary conformal field theory and show that in this description this state can be regarded as a non-supersymmetric D0-brane in type I string theory. This construction can be generalised to represent the D0-brane in type IIA string theory as a vortex solution of the tachyon field on the membrane anti-membrane pair, and the D-string of type I string theory as a topological soliton of the tachyon field on the D5-brane anti-D5-brane pair.

Vortex Pair Creation on Brane-Antibrane Pair via Marginal Deformation
It has been conjectured that the vortex solution on a D-brane anti-D-brane system represents a D-brane of two lower dimension. We establish this result by first identifying a series of marginal deformations which create the vortex antivortex pair on the brane antibrane system, and then showing that under this series of marginal deformations the original D-brane anti-D-brane system becomes a D-b...
متن کاملBrane Descent Relations in K - theory
The various descent and duality relations among BPS and non-BPS D-branes are classified using topological K-theory. It is shown how the descent procedures for producing type-II D-branes from brane-antibrane bound states by tachyon condensation and (−1)L projections arise as natural homomorphisms of K-groups generating the brane charges. The transformations are generalized to type-I theories and...

متن کاملBrane - Antibrane as a Defect of Tachyon Condensation
In a tachyon effective field theory of a non-BPS brane, we construct a classical solution representing a parallel brane-antibrane. The solution is made of a kink and an antikink placed at antipodal points of S. Estimation of the brane energy shows the appearance of an excitation of a string connecting the two branes, even though the theory is Abelian. We performed fluctuation analysis around th...
متن کاملA Note on Non-Commutative Field Theory and Stability of Brane-Antibrane Systems
It has been conjectured that a pair ofD5−D5 branes wrapped on some non-trivial two cycle of a Calabi-Yau manifold becomes a stable BPS D3 brane in the presence of a very large B field and magnetic fluxes on their worldvolumes. We discuss this by considering the non-commutative field theory on the worldvolume of the pair of branes whose field multiplication is made with respect to two different ...
