We report on mass and lifetime measurements of several ground state charmed and bottom baryons, using a data sample corresponding to $9.6\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ from $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ and recorded with the Collider Detector at Fermilab. Baryon candidates are reconstructed from data collected with an online event selection designed for the collection of long-lifetime heavy-flavor decay products and a second event selection designed to collect $J/\ensuremath{\psi}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ candidates. First evidence for the process ${\mathrm{\ensuremath{\Omega}}}_{b}^{\ensuremath{-}}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Omega}}}_{c}^{0}{\ensuremath{\pi}}^{\ensuremath{-}}$ is presented with a significance of $3.3\ensuremath{\sigma}$. We measure the following baryon masses: $M({\mathrm{\ensuremath{\Xi}}}_{c}^{0})=2470.85\ifmmode\pm\else\textpm\fi{}0.24(\text{stat})\ifmmode\pm\else\textpm\fi{}0.55(\text{syst})\text{ }\text{ }\mathrm{MeV}/{c}^{2},\phantom{\rule{0ex}{0ex}}M({\mathrm{\ensuremath{\Xi}}}_{c}^{+})=2468.00\ifmmode\pm\else\textpm\fi{}0.18(\text{stat})\ifmmode\pm\else\textpm\fi{}0.51(\text{syst})\text{ }\text{ }\mathrm{MeV}/{c}^{2},\phantom{\rule{0ex}{0ex}}M({\mathrm{\ensuremath{\Lambda}}}_{b})=5620.15\ifmmode\pm\else\textpm\fi{}0.31(\text{stat})\ifmmode\pm\else\textpm\fi{}0.47(\text{syst})\text{ }\text{ }\mathrm{MeV}/{c}^{2},\phantom{\rule{0ex}{0ex}}M({\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}})=5793.4\ifmmode\pm\else\textpm\fi{}1.8(\text{stat})\ifmmode\pm\else\textpm\fi{}0.7(\text{syst})\text{ }\text{ }\mathrm{MeV}/{c}^{2},\phantom{\rule{0ex}{0ex}}M({\mathrm{\ensuremath{\Xi}}}_{b}^{0})=5788.7\ifmmode\pm\else\textpm\fi{}4.3(\text{stat})\ifmmode\pm\else\textpm\fi{}1.4(\text{syst})\text{ }\text{ }\mathrm{MeV}/{c}^{2},\phantom{\rule[-0.0ex]{1em}{0.0ex}}\text{and}\phantom{\rule{0ex}{0ex}}M({\mathrm{\ensuremath{\Omega}}}_{b}^{\ensuremath{-}})=6047.5\ifmmode\pm\else\textpm\fi{}3.8(\text{stat})\ifmmode\pm\else\textpm\fi{}0.6(\text{syst})\text{ }\text{ }\mathrm{MeV}/{c}^{2}.$The isospin splitting of the ${\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-},0}$ states is found to be $M({\mathrm{\ensuremath{\Xi}}}_{b}^{\ensuremath{-}})\ensuremath{-}M({\mathrm{\ensuremath{\Xi}}}_{b}^{0})=4.7\ifmmode\pm\else\textpm\fi{}4.7(\text{stat})\ifmmode\pm\else\textpm\fi{}0.7(\text{syst})\text{ }\mathrm{MeV}/{c}^{2}$.
