An interacting fermion-antifermion pair in the spacetime background generated by static cosmic string

Effects of Rotating Frame on a Vector Boson Oscillator

“…Even though these spacetime backgrounds are locally flat [9][10][11] out of the intersection point, they are not flat when viewed globally [9][10][11]. Because of this feature, the cosmic strings can be responsible for several physical events in the universe [12][13][14][15]. The spacetime background of the cosmic string is characterized by parameter, which is angular deficit parameter depending on the linear mass density ( ) of the cosmic string [12][13][14][15].…”
