We present the results of a search for pair production of scalar bottom quarks ($\tilde b_1$) and scalar third-generation leptoquarks ($LQ_3$) in a data sample of 5.2 $fb^{-1}$ collected by the D0 experiment at the Tevatron, the $p\bar{p}$ collider at Fermilab. We assume that sbottoms decay to a neutralino ($\tilde \chi^0_1$) and a b quark, and we set 95% C.L. lower limits on their production in the ($m_{\tilde b_1}$, $m_{\tilde \chi^0_1}$) mass plane such that $m_{\tilde b_1} > 247$ GeV for $m_{\tilde \chi^0_1} = 0$ and $m_{\tilde \chi^0_1} > 110$ GeV for $160 < m_{\tilde b_1} < 200$ GeV. The leptoquarks are assumed to decay to a tau neutrino and a b quark, and we set a 95% C.L. lower limit of 247 GeV on the mass of a charge-1/3 third-generation leptoquark.
