Abstract

The existance of cosmic strings does not contradict to the current observational cosmological data. From theoretical point of view the cosmic strings can be of the different origins and type and be characterized by wide range of energies. The cosmic superstrings naturally arise in the brane-world scenario. The paper is devoted to discussing possible cosmological observational tests on superstring theory, and to the identification of observational properties allowing to distinguish between cosmological superstring of different type. In the paper we obtained a lower limit on the superstring tension as function of the deficit angle.

Keywords
