Cylindrical Thin-shell Wormholes in $f(R)$ gravity

In this paper, we employ cut and paste scheme to construct thin-shell wormhole of a charged black string with $f(R)$ terms. We consider $f(R)$ model as an exotic matter source at wormhole throat. The stability of the respective solutions are analyzed under radial perturbations in the context of $R+δR^2$ model. It is concluded that both stable as well as unstable solutions do exist for different values of $δ$. In the limit $δ{\rightarrow}0$, all our results reduce to general relativity.
