Properties of Heavy Flavor Hadrons in ATLAS

The LHC will offer an opportunity for study of QCD at unprecedented energy scales. ATLAS, which will cover central proton-proton collisions, plans to study heavy flavor hadrons including quarkonium states. The expected statistics will permit high precision measurements of production polarization of the Lambda_b and J/psi. We also present new studies of production mechanisms, lifetime, and branching ratios for decays in the B_c and Upsilon systems and a program of studies of chi_b decays to resonant and non-resonant states.
