Description

Local interaction of strings with internal spin with external scalar field is considered as an interaction through the virtual point-like closed string. The interaction amplitude of this state with any number of open strings in ground states is constructed. For scalar form factor of the ground state the asymptotic behaviour 1/q2 under transferred momenta is obtained. The elastic amplitude 2→2 properties with one scalar closed string emission into vacuum are investigated, in particular a power decrease for large angle scattering field is obtained
