Relativistic quantum motion of the scalar bosons in the background space time around a chiral cosmic string

In this paper, a relativistic behavior of spin-zero bosons is studied in a chiral cosmic string space-time. The Duffin-Kemmer-Petiau (DKP) equation and DKP oscillator are written in this curved space-time and are solved by using an appropriate ansatz and the Nikiforov-Uvarov method, respectively. The influences of the topology of this space-time on the DKP spinor and energy levels and current density are also discussed in detail.
