Tachyonic Modes on Type 0 Ns5-branes
نویسنده
چکیده
Via T-duality, a stack of unwrapped type 0 NS5-branes is transformed into a Kaluza-Klein monopole with An type singularity at its center. The spectrum of twisted modes at the singularity contains tachyonic modes. We show that, in certain parameter region, this tachyonic spectrum is completely reproduced as modes of the bulk tachyon field localized on a classical NS5-brane solution. In passing, we show how twisted modes at the singularity reproduce gauge fields on stacks of NS5-branes.

Fundamental strings and NS5-branes from unstable D-branes in supergravity
By using the non-supersymmetric p-brane solutions delocalized in arbitrary number of transverse directions in type II supergravities, we show how they can be regarded as interpolating solutions between unstable Dp-branes (a non-BPS D-brane or a pair of coincident D-brane-antiD-brane) and fundamental strings and also between unstable Dp-branes and NS5-branes. We also show that some of these solu...
متن کاملGeometrical Tachyon Kinks and NS 5 Branes
We further investigate the NS5 ring background using the tachyon map. Mapping the radion fields to the rolling tachyon helps to explain the motion of a probe Dp-brane in this background. It turns out that the radion field becomes tachyonic when the brane is confined to one dimensional motion inside the ring. We find explicit solutions for the geometrical tachyon field that describe stable kink ...
متن کاملQcd Dynamics from M-theory
A large literature has grown up on engineering supersymmetric field theories using D-brane constructions in type IIA string theory (a comprehensive review and list of references is to be found in ref 2). The essential ingredient is that the massless string modes of strings ending on the surfaces of D-branes correspond to gauge fields living on the D-branes’ surfaces, plus superpartners. In addi...
متن کاملBranes in type 0/type II duality
We give relations between type 0 and type II D-brane configurations under Tduality suggested by Bergman and Gaberdiel and confirm that massless fields on D-branes are identical to ones on the dual D-brane configurations. Furthermore, we discuss dualities of type 0 and type II NS5-branes. ∗[email protected]
متن کاملNS Fivebranes in Type 0 String Theory ∗
The massless degrees of freedom of type 0 NS5-branes are derived. A non-chiral, purely bosonic spectrum is found in both type 0A and 0B. This non-chirality is confirmed by a one-loop computation in the bulk. An interpretation of the spectra in terms of “type 0 little strings” is proposed. The type 0B NS5-brane is conjectured to be dual to a bound state of certain D5-branes, which is argued to h...
