Abstract	In this study we search for decays $B^0\rightarrow X_c^- \Lambda^0 K^+$ and $B^0\rightarrow \overline{X}_c^0 \Lambda^0 K_s^0$ in Belle, where $X_c$ represents a charm baryon. Belle collected data at a center of mass energy close to $\Upsilon(4S)$ resonance, which decays only to two B mesons almost every time. We follow a recoil approach where the other $B$ meson is reconstructed in various hadronic modes, and the charm baryon is looked for in the recoil of the accompanying $\Lambda^0$ and $K/K_s$ coming from signal $B$. This study will provide a comprehensive insight into $B\rightarrow$ baryonic decays and the impact of $s\bar{s}$ quark pair production on the branching fractions.
