Description
ATLAS has performed searches for heavy hadrons, with results
including the first observation of the chi_b(3P) Bottomonium
states. New results in this program are discussed, including
searches for excited b-hadrons and new decay modes of b-hadrons
as well as the bottomonium counterpart of X(3872). We also review
ATLAS studies of B-hadron decays, including the measurement of the
parity violating asymmetry parameter alpha_b in Lambda_b -> Lambda J/psi,
obtained from the study of angular correlations in the p pi- mu+ mu-
final state. The measurement is compared to predictions based on
perturbative QCD and heavy quarks effective theory.
