Cosmic D- and DF-strings from D3D̄3: Black Strings and BPS Limit
We study Dand DF-strings in a D3D̄3 system in the context of Dirac-Born-Infeld type effective field theory. In the presence of an electric flux from a transverse direction, we discuss gravitating thick D-string solutions of a spatial manifold, S2 × R1, in which straight D-strings stretched along the R1 direction are attached to the south and north poles of the two-sphere. There is a horizon alon...
متن کاملCosmic D- and DF-strings from D3D̄3: Black Strings and BPS Bound
We study Dand DF-strings from D3D̄3 in the context of Dirac-Born-Infeld type effective field theory. In the presence of an electric flux from a transverse direction, gravitating thick D-string solutions form a spatial manifold, S2×R1, and straight D-strings stretched along the R1 direction are located at the south and north poles of the two-sphere. There is a horizon along its equator and then t...
متن کاملDF-strings from D3D̄3 as Cosmic Strings
We study Dirac-Born-Infeld type effective field theory of a complex tachyon and U(1)×U(1) gauge fields describing a D3D̄3 system. Classical solutions of straight global and local DFstrings with quantized vorticity are found and are classified into two types by the asymptotic behavior of the tachyon amplitude. For sufficiently large radial distances, one has linearlygrowing tachyon amplitude and ...
متن کاملCosmic F- and D-strings
Macroscopic fundamental and Dirichlet strings have several potential instabilities: breakage, tachyon decays, and confinement by axion domain walls. We investigate the conditions under which metastable strings can exist, and we find that such strings are present in many models. There are various possibilities, the most notable being a network of (p, q) strings. Cosmic strings give a potentially...
متن کاملBPS Bound of Multi - D - and DF - strings in Boundary String Field Theory
A BPS bound is systematically derived for straight multi-D-and DF-strings from the D3 ¯ D3 system in the context of boundary superstring field theory. The BPS limit is obtained in the limit of thin D(F)-strings, where the Bogomolnyi equation supports singular static multi-D(F)-string solutions. For the BPS multi-string configurations with arbitrary separations , BPS sum rule is fulfilled under ...
