Traversable Wormholes in $R+αR^n$ Gravity

In this work, the study of traversable wormholes in $f(R)$ gravity with the function $f(R)=R+αR^n$, where $α$ and $n$ are arbitrary constants, is taken into account. The shape function $b(r)=\frac{r}{\exp(r-r_0)}$, proposed by Samanta et al. \cite{godani1}, is considered. The energy conditions with respect to both constant and variable redshift functions are discussed and the existence of wormhole solutions without presence of exotic matter is investigated.
