Abstract

ATLAS has a wide program to study the production properties of conventional and exotic quarkonium, beauty, and charm bound states. We present the latest results on $J/\psi$ prompt and non-prompt components at $\sqrt{s}=$ 7, 8 and 13 TeV, open charm production at at $\sqrt{s}=$ 7 TeV, the ratio $f_s/f_d$ of $b$-quark fragmentation fractions at $\sqrt{s}=$ 7 TeV, $B$ meson production at $\sqrt{s}=$ 13 TeV and the observation of $\Lambda_b^0 \rightarrow \psi(2S)\Lambda^0$ at $\sqrt{s}=$ 8 TeV.
