A measurement of $\psi(2\mathrm{S})$ production cross-section in $\psi(2\mathrm{S})\rightarrow J/\psi(\to\mu^+\mu^-)\pi^+\pi^-$ decay with ATLAS detector

The thesis describes the prompt and non-prompt production cross-sections for $\psi(2\mathrm{S})$ mesons, using 2.1~fb$^{-1}$ of 2011 proton-proton collision data at a centre-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. The measurement uses the decay mode $\psi(2\mathrm{S})\r...
