Correlation strength $b_{corr}$ as a function of $\eta_{\rm gap}$ in pp collisions fordata taken from Fig.\,\ref{fig:fullPhiAllWindows}and compared to MC generators PYTHIA Perugia 0 (solid line), Perugia 2011 (dotted line) and PHOJET(dashed line) for $\sqrt{s}=0.9$, 2.76 and 7 TeV collision energies,windows width $\deta$ is 0.2. The bottom panelsshow the ratio of the data to MC.
