Open string pair production from the interacting dressed-angled D-strings

We calculate the rate of the open string pair production from the interaction of two non-intersecting D-strings at angle. The D-strings have been equipped with the U(1) gauge potentials in the presence of the Kalb-Ramond field. This rate will be discussed when the D-strings intersect each other. Our computations is in the framework of the bosonic string theory.
