# Interactions of cosmic superstrings

@article{Jackson2007InteractionsOC, title={Interactions of cosmic superstrings}, author={Mark G. Jackson}, journal={Journal of High Energy Physics}, year={2007}, volume={2007}, pages={035-035} }

We develop methods by which cosmic superstring interactions can be studied in detail. These include the reconnection probability and emission of radiation such as gravitons or small string loops. Loop corrections to these are discussed, as well as relationships to (p; q)-strings. These tools should allow a phenomenological study of string models in anticipation of upcoming experiments sensitive to cosmic string radiation.

Superstring theory posits that as complicated as nature may seem to the naive observer,
the variety of observed phenomena may be explained by postulating that at the fundamental

Macroscopic fundamental and Dirichlet strings have several potential instabilities: breakage, tachyon decays, and confinement by axion domain walls. We investigate the conditions under which…
