Measurements of the $\chi_c$ and $\chi_b$ quarkonium states in $pp$ collisions with the ATLAS experiment
The $\chi_b$ bottomonium states are observed through the reconstruction of the ra diative decays $\chi_b(nP)\rightarrow\Upsilon(1S)\,\gamma$ using $4.4\,\rm{fb}^{−1}$ of $pp$ collision data collected at $\sqrt{s} = 7\,\rm{TeV}$ with the ATLAS experiment. The production of the $\chi_b(1P)$ and $\chi_...
