### Description

The D0 collaboration has recently reported evidence for a possible four-quark state named $X(5568)$ in the decay sequence $X(5568) \rightarrow B_s^0 \pi^{\pm}$, $B_s^0 \rightarrow J/\psi \phi$. Here we present a progress report on our search for the $X(5568)$ with semileptonic decays of the $B_s^0$ meson. We also report on a search for a strange pentaquark decaying to a $J/\psi \Lambda$ pair. The studies are based on $10.4~\rm{fb^{-1}}$ of $p \overline p$ collision data at $\sqrt{s}$ = 1.96 TeV collected by the D0 experiment at the Fermilab Tevatron collider.
