title: "Figure 2 (left) Data" of "Study of J/$\psi$ meson production from jet fragmentation in pp collisions at $\sqrt{s} =$ 8 TeV"

description: Experimental Xi values and FJF predictions for the four NRQCD terms using BCKL LDME parameters
description: Abstract: A study of the production of J/psi mesons in association with jets in proton-proton collisions at CM energy of 8~TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 inverse femtobarns collected with the CMS detector at the LHC. For events with at least one observed jet, the angular separation between the J/psi meson and the jet is used to test whether the meson is a jet fragment. The differential distributions of the jet fragmentation probability as a function of jet energy for a fixed J/psi energy fraction are presented. The experimental results are compared to a theoretical model using the fragmenting jet function (FJF) approach. The jet fragmentation data agree with the predictions of the FJF calculations that use specific long-distance matrix element parameters. This agreement shows that the combination of data on jet fragmentation to J/psi mesons and FJF analysis is a new way to test predictions for J/psi meson production from nonrelativistic quantum chromodynamics. The results indicate that the jet fragmentation mechanism produces unpolarized J/psi mesons. The analysis also shows that most J/psi mesons with energy above 15 GeV and rapidity |y|&lt;1.0 are fragments of jets with pseudorapidity &lt; 1.

title: "$\cos\theta_{1}^{k}$" of "Measurement of the top quark polarization and $\mathrm{t\bar{t}}$ spin correlations using dilepton final states in proton-proton collisions at $\sqrt{s} =$ 13 TeV"

description: Figure 4, normalized differential cross section for $\cos\theta_{1}^{k}$
description: Unfolded normalized differential cross sections for angular observables sensitive to the top quark polarization and $t\bar{t}$ spin correlations measured in dileptonic $t\bar{t}$ events at CMS, and the corresponding extracted coefficients and values of $f_\text{SM}$.

Statistical and systematic covariance matrices are given for all measured bins (or coefficients) together, in the same order as the distributions are given on this page.

Care must be taken in the choice of distributions for simultaneous fitting. When using a simple $\chi^2$ minimization procedure, the statistical uncertainty in the fitted parameter can be reduced by adding to the fit an observable which has little or no sensitivity to the fitted parameter, but which is not independent of the other observables in the fit. This problem can be avoided by requiring the set of fitted observables to be mutually independent. For example, $\cos\theta_{1}^{k}$ and $\cos\theta_{1}^{k*}$ should not be used together, because $|\cos\theta_{1}^{k}|=|\cos\theta_{1}^{k*}|$.
