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.

We explain simple semi-classical rules to estimate the lifetime of any given highly excited quantum state of the string spectrum and apply them to identify new long-lived string states. Using
We make an attempt to dynamically study, in four space-time dimensions, the classical gravitational collapse of a macroscopic circular fundamental string, by a truncation of the Einstein equations
In this paper we present semiclassical computations of the splitting of folded spinning strings in ${\mathrm{AdS}}_{3}$, which may be of interest in the context of AdS/CFT duality. We start with a
Using integrability we reduce the problem of constructing general classical splitting string solutions on R ×S 3 to a series of Birkhoff factorization problems. Namely, given any incoming string

We investigate the tunnelling of spin-1/2 particles through event horizons. We first apply the tunnelling method to Rindler spacetime and obtain the Unruh temperature. We then apply fermion

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.

There are two main reasons for the recent renewal of interest in cosmic strings: Fundamental string-theory models suggest their existence; and there are at least two tentative observations of their
