Classification of simple quasifinite modules for contact superconformal algebras with $N\ne4$

In this paper, we classify all simple jet modules for contact superconformal algebras $\mathcal{K}(N;\epsilon)$ with $N\neq4$. Then all simple quasifinite modules for $\widehat{\mathcal{K}}(N;\epsilon)$ ($N\neq4$), the universal central extension of $\mathcal{K}(N;\epsilon)$, are classified. Our results show that Mat\'{i}nez-Zelmanov's conjecture in \cite{MZe1} holds for $\mathcal{K}(N;\epsilon)$ ($N\ne4$).
