title: "Table 21" of "Multipion Bose-Einstein correlations in pp, p-Pb, and Pb-Pb collisions at the LHC"

description: Same charge 4-pion expected correlations in PbPb collisions projected against Q4. 0-5% Centrality.
description: CERN-LHC. Three- and four-pion Bose-Einstein correlations are presented in pp, p-Pb, and Pb-Pb collisions at the LHC. We compare our measured four-pion correlations to the expectation derived from two- and three-pion measurements. Such a comparison provides a method to search for coherent pion emission. We also present mixed-charge correlations in order to demonstrate the effectiveness of several analysis procedures such as Coulomb corrections. Same-charge four-pion correlations in pp and p-Pb appear consistent with the expectations from three-pion measurements. However, the presence of non-negligible background correlations in both systems prevent a conclusive statement. In Pb-Pb collisions, we observe a significant suppression of three- and four-pion Bose-Einstein correlations compared to expectations from two-pion measurements. There appears to be no centrality dependence of the suppression within the 0-50% centrality interval. The origin of the suppression is not clear. However, by postulating either coherent pion emission or large multibody Coulomb effects, the suppression may be explained.

title: "Table 1" of "Measurement of the exclusive $\Upsilon$ production cross-section in $pp$ collisions at $\sqrt{s}=$7 TeV and 8 TeV"

description: Production cross-section for the $\Upsilon(1S)$ resonance in ranges of $\Upsilon(1S)$ rapidity, where the muons are required to lie in the pseudorapidity range $2 &lt; \eta(\mu^{\pm}) &lt; 4.5$. The first uncertainties are statistical and the second ones are systematic.
description: CERN-LHCb. A study is presented of central exclusive production of $\Upsilon(nS)$ states, where the $\Upsilon(nS)$ resonances decay to the $\mu^{+} \mu^{-}$ final state, using $pp$ collision data recorded by the LHCb experiment. The cross-section is measured in the rapidity range $2 &lt; y(\Upsilon) &lt; 4.5$ where the muons are reconstructed in the pseudorapidity range $2 &lt; \eta(\mu^{\pm}) &lt; 4.5$. The data sample corresponds to an integrated luminosity of 2.9 fb$^{-1}$ and was collected at centre-of-mass energies of 7 TeV and 8 TeV. The measured $\Upsilon(1S)$ and $\Upsilon(2S)$ production cross-sections are
\[
\sigma(pp \to p\Upsilon(1S)p) = 9.0 \pm 2.1 \pm 1.7 \text{ pb}
\]
and
\[
\sigma(pp \to p\Upsilon(2S)p) = 1.3 \pm 0.8 \pm 0.3 \text{ pb},
\]
where the first uncertainties are statistical and the second are systematic. The $\Upsilon(1S)$ cross-section is also measured as a function of rapidity and is found to be in good agreement
with Standard Model predictions. An upper limit is set at 3.4 pb at the 95% confidence level for the exclusive $\Upsilon(3S)$ production cross-section, including possible contamination
from $\chi_b(3P) \to \Upsilon(3S)\gamma$ decays.

title: "Table 1" of "Comparison of the Z/gamma*+jets to gamma+jets cross sections in pp collisions at sqrt(s)= 8 TeV"

description: The Z boson differential transverse momentum cross-section in an inclusive $Z/\gamma^{*}+\mathrm{jets}$, $N_{\mathrm{jets}} \geq1$ selection.
description: CERN-LHC. A comparison of the differential cross sections for the processes $Z/\gamma^{*}+\text{jets}$ and photon $(\gamma)+\text{jets}$ is presented. The measurements are based on data collected with the CMS detector at $\sqrt{s}=8$\TeV corresponding to an integrated luminosity of 19.7\fbinv. The differential cross sections and their ratios are presented as functions of \pt. The measurements are also shown as functions of the jet multiplicity. Differential cross sections are obtained as functions of the ratio of the $Z/\gamma^{*}$ \pt to the sum of all jet transverse momenta and of the ratio of the $Z/\gamma^{*}$ \pt to the leading jet transverse momentum. The data are corrected for detector effects and are compared to simulations based on several QCD calculations.
 
For $Z/\gamma^{*}$ plus jets events we select:
- two same flavour opposite sign leptons with $p_{T} &gt; 20$ GeV and $|\eta| &lt; 2.4$ and $71 &lt; M_{\ell\ell} &lt; 111 $ GeV and $p_{T}^{\ell\ell} &gt; 100$ GeV
- leptons are "dressed" with all photons in a cone of radius $\Delta R = 0.1$
- at least one jet, jet selection $p_{T} &gt; 30$ GeV and $|\eta| &lt; 2.4$, we remove jets within a radius of $\Delta R &lt; 0.5$ with respect to the axes of each lepton
- for the ratio plots a cut on Z rapidity |y|&lt;1.4 is also applied

For $\gamma$ plus jets events we select:
- at least a prompt photon with $p_{T} &gt; 100$ GeV and $|\eta| &lt; 1.4$ (in case there is more than one photon the leading one satisfying all cuts is used)
- the photon must be isolated, i.e. the scalar sum of the $p_T$ of all stable particle in a cone of radius $\Delta R = 0.4$ is less then 5 GeV
- at least one jet, jet selection $p_{T} &gt; 30$ GeV and $|\eta| &lt; 2.4$ , we remove jets within a radius of $\Delta R &lt; 0.5$ with respect to the axis of the photon.
