    Abstract

    We study the embedding of cosmic strings, related to the Abrikosov-Nielsen-Olesen vortex solution, into d = 4, N = 1 supergravity. We find that the local cosmic string solution which saturates the BPS bound of supergravity with D-term potential for the Higgs field and with constant Fayet-Iliopoulos term, has 1/2 of supersymmetry unbroken. We observe an interesting relation between the gravitino supersymmetry transformation, positive energy condition and the deficit angle of the cosmic string. We argue that the string solutions with magnetic flux with F-term potential cannot be supersymmetric, which leads us to a conjecture that D1-strings (wrapped D1+q-branes) of string theory in the effective 4d supergravity are described by the D-term strings that we study in this paper. We give various consistency checks of this conjecture, and show that it highlights some generic properties of non-BPS string theory backgrounds, such as brane-anti-brane systems. Supersymmetry breaking by such systems can be viewed as FI D-term breaking, which implies, under certain conditions, the presence of gauged R-symmetry on such backgrounds. The D-term nature of the brane-anti-brane energy can also provide information on the superpotential for the tachyon, which Higgses the R-symmetry. In this picture, the interbrane force can be viewed as a result of the world-volume gauge coupling renormalization by the open string loops.
