Local currents in dual string theory

The local interactions of strings with an external scalar current are considered in the framework of the Nambu dual string model as interactions mediated by virtual states of a closed pointlike string. The amplitude for the interaction of such a current with an arbitrary number of strings with free ends in ground states is presented. The asymptotic properties of a ground-state open-string form factor are investigated for large momentum transfers. The amplitude for the interaction of a local current with an arbitrary number of closed ground-state strings is obtained.
