Description
Recent results on $B_{c}$ production and decays from the proton-proton collision data taken by the ATLAS experiment will be presented. The measurement of the differential ratios of $B_{c}^{+}$ and $B^{+}$ production cross sections at 8 TeV will be shown. New results on $B_{c}$ decays to $J/\psi D_{s}^{(*)}$ final states obtained with the Run 2 data at 13 TeV will also be reported.
