Measurement of Y(nS) production at 7 TeV at the CMS experiment
The $\Upsilon(\text{nS})$ production cross section in proton-proton collisions at $\sqrt{s} = 7$\,TeV is measured using the CMS detector at the LHC from data corresponding to $(3.1 \pm 0.3)\,\text{pb}^{-1}$ of integrated luminosity. In the rapidity range $\lvert y\rvert< 2$, we find that $\sigma...

description | The $\Upsilon(\text{nS})$ production cross section in proton-proton collisions at $\sqrt{s} = 7$\,TeV is measured using the CMS detector at the LHC from data corresponding to $(3.1 \pm
0.3)\,\text{pb}^{-1}$ of integrated luminosity. In the rapidity range $\lvert y\rvert< 2$, we find that $\sigma(\text{pp}\rightarrow\Upsilon(1\text{S})X)\cdot\mathcal{B} (\Upsilon(1\text(S))\rightarrow\mu^+\mu^-) = (7.37 \pm 0.13 ^{+0.61}_{-0.42} \pm 0.81)$\,nb, where the uncertainties are statistical, systematic and luminosity, respectively. We also report differential cross sections for the three lowest $\Upsilon$ states as a function of transverse momentum and rapidity and compare them with other experiments and model predictions. |
