# Black hole formation from collisions of cosmic fundamental strings

@article{Iengo2006BlackHF, title={Black hole formation from collisions of cosmic fundamental strings}, author={Roberto Iengo and Jorge G Russo}, journal={Journal of High Energy Physics}, year={2006}, volume={2006}, pages={079-079} }

We develop the general formalism for joining, splitting and interconnection of closed and open strings. As an application, we study examples of fundamental cosmic string collisions leading to gravitational collapse. We find that the interconnection of two strings of equal and opposite maximal angular momentum and arbitrarily large mass generically leads to the formation of black holes, provided their relative velocity is small enough.

There are important kinematical constraints on the process of intercommuting of two straight strings in which they exchange partners but become joined by a third string and it is shown that the exchange cannot occur if the strings meet with very large relative velocity.
