Conventional and exotic charmonium production at the ATLAS experiment

We present detailed precision measurements of the prompt and non-prompt differential production cross sections for the $\psi(2S)$, $\chi_{c1}$, and $\chi_{c2}$ charmonium states at $\sqrt{s}=7\,\mathrm{TeV}$. The related differential cross section measurements for the $\Upsilon(nS)$ states ($n=1,2,3...

Sumario:We present detailed precision measurements of the prompt and non-prompt differential production cross sections for the $\psi(2S)$, $\chi_{c1}$, and $\chi_{c2}$ charmonium states at $\sqrt{s}=7\,\mathrm{TeV}$. The related differential cross section measurements for the $\Upsilon(nS)$ states ($n=1,2,3$) are also presented. The results are compared with leading theoretical models. The methods of the $\Upsilon$ measurement have been extended to search for a hidden-beauty analogue of the $X(3872)$, in the decay mode $X_{\text{b}} \to \pi^+ \pi^- \Upsilon(1S)$. The results of this search are also presented. [Original abstract submitted to conference: We present detailed precision measurements of the prompt and non-prompt differential production cross sections for the $J/\psi$, $\psi(2S)$, $\chi_c$ and $X(3872)$ charmonium states at $\sqrt{s}=8\,\mathrm{TeV}$, covering $J/\psi$ and $\psi(2S) \to J/\psi \pi^+\pi^-$ J/ψ and $\chi_c$. The results are compared with leading theoretical models.]
