Detecting new hadrons or excited ones

We review Tevatron Run II results of heavy quark hadron searches, including measurements of $B_c$, B^{**}$, and $B_s^{**}$ mesons as well as $Sigma_b$, $Sigma_b^*$, $Xi_b^-$, and $Omega_b^-$ baryons. We discuss prospects of those measurements at LHC experiment ATLAS and review some basic selection methods. ATLAS 2009 early data are used to illustrate ATLAS performance of $K_s opi^+pi^-$, $Lambda o ppi^-$, and $arLambda o ar ppi^+$ decays reconstruction, which will be final state particles in some of the heavy hadron decays. In addition some of the promising new heavy baryon decays are reviewed.
