A Note on the evolution of cosmic string/superstring networks

In the context of brane world scenario, cosmic superstrings can be formed in D-brane annihilation at the end of the brane inflationary era. This cosmic superstring network has a scaling solution and the characteristic scale of the network is proportional to the square root of the reconnection probability. PACS numbers: 11.25.-w, 11.25.Uv, 11.27.+d A Note on the evolution of cosmic string/supers...

Brane inflation predicts the production of cosmic superstrings with tension 10 −12 < ∼ Gµ < ∼ 10 −7. Superstring theory predicts also the existence of a dilaton with a mass that is at most of the order of the gravitino mass. We show that the emission of dilatons imposes severe constraints on the allowed evolution of a cosmic super-string network. In particular, the detection of gravitational wa...

Cosmic superstrings are introduced to non-experts. First D-branes and (p, q) strings are discussed. Then we explain how tachyon condensation in the early universe may have produced F, D and (p, q) strings. Warped geometries which can render horizon sized superstrings relatively light are discussed. Various warped geometries including the deformed conifold in the Klebanov-Strassler geometry are ...

In this work, we present the gravitational field generated by a cosmic string carrying a timelike current in the scalar-tensor gravities. The mechanism of formation and evolution of wakes is fully investigated in this framework. We show explicitly that the inclusion of electromagnetic properties for the string induces logarithmic divergences in the accretion problem.
