Measurement of the production cross-section of $J/\psi $ and $\psi (2{\textrm{S}})$ mesons in pp collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
Measurements of the differential production cross-sections of prompt and non-prompt $J/\psi$ and $\psi(2$S$)$ mesons with transverse momenta between 8 and 360 GeV and rapidity in the range $|y|<2$ are reported. Furthermore, measurements of the non-prompt fractions of $J/\psi$ and $\psi(2$S$)$, and the prompt and non-prompt $\psi(2$S$)$-to-$J/\psi$ production ratios, are presented. [...]

Measurement of $CP$ violation and mixing in $B_s^0 \to J/\psi\phi$ in ATLAS / Jakoubek, Tomas (Institute of Physics of the Czech Academy of Sciences)
An overview of a measurement of time-dependent $CP$ asymmetry parameters in $B_s^0 \to J/\psi(\mu^+\mu^-)\phi(K^+K^-)$ decays using 80.5 fb$^{-1}$ of integrated luminosity collected with the ATLAS detector from 13 TeV $pp$ collisions at the LHC is presented. [...]

Production and Properties of B-Hadrons with the ATLAS Detector / Reznicek, Pavel (Charles University, Faculty of Mathematics and Physics, Prague) /ATLAS Collaboration
A wide program of studies on heavy flavours is performed with the ATLAS detector. Production cross sections have been measured for hadrons with b and c quark, for quarkonia states, and for associated production J/psi+J/psi, J/psi+muon, J/psi+W and J/psi+Z. [...]

Vector boson and quarkonia production in lead-lead collisions with ATLAS detector / Gallus, Petr (CTU, Prague)
Photons and weak bosons do not interact strongly with the dense and hot medium formed in the nuclear collisions, thus should be sensitive to the nuclear modification of parton distribution functions (nPDFs). [...]

Vector boson and quarkonia production in p+Pb and Pb+Pb collisions with ATLAS at the LHC / Gallus, Petr (Czech Technical University in Prague) /ATLAS Collaboration
Photons and weak bosons do not interact strongly with the dense and hot medium formed in the nuclear collisions, thus should be sensitive to the nuclear modification of parton distribution functions (nPDFs). The in-medium modification of heavy quarkonium states plays an important role in studying the hot and dense medium formed in the larger collision systems. [...]
