Abstract
We present a selection of recent heavy-flavour measurements by the ATLAS experiment using data collected during 2011 and 2012. The results include first analysis of associated production of J/psi with Z boson, measurement of asymmetry parameter and helicity amplitudes in Lambda(0)(b) -> J/psi Lambda(0) decay and a study of B-c(+) -> J/psi D-s((*)+) decays.
Moreover, the first observation of an excited B-c(+/-) meson state and results of a search for the X-b and other hidden-beauty states are also shown.
