Collisions of Cosmic F- and D-strings
Mark G. Jackson, Nicholas T. Jones, Joseph Polchinski
Recent work suggests that fundamental and Dirichlet strings, and their (p,q) bound states, may be observed as cosmic strings. The evolution of cosmic string networks, and therefore…
Adding a Brane to the Brane-Anti-Brane Action in BSFT
Nicholas T. Jones, Louis Leblond, S. -H. Henry Tye
We attempt to generalize the effective action for the D-brane-anti-D-brane system obtained from boundary superstring field theory (BSFT) by adding an extra D-brane to it to obtain…
Spectral flow and boundary string field theory for angled D-branes
Nicholas T. Jones, S. -H. Henry Tye
D-branes intersecting at an arbitrary fixed angle generically constitute a configuration unstable toward recombination. The reconnection of the branes nucleates at the intersection…
The Production, Spectrum and Evolution of Cosmic Strings in Brane Inflation
Nicholas T. Jones, Horace Stoica, S. -H. Henry Tye
Brane inflation in superstring theory predicts that cosmic strings (but not domain walls or monopoles) are produced towards the end of the inflationary epoch. Here, we discuss the…
An Improved Brane Anti-Brane Action from Boundary Superstring Field Theory and Multi-Vortex Solutions
Nicholas T. Jones, S. -H. Henry Tye
We present an improved effective action for the D-brane-anti-D-brane system obtained from boundary superstring field theory. Although the action looks highly non-trivial, it has si…
