Measured (left) particle density, and (right) $\Sigma \pt$ density, in the transverse region relative to the leading charged-particle jet in the event ($\abs{\eta}<2$, $60\de < \abs{\Delta \varphi} < 120\de $), as a function $\jetpt$. The data (symbols) are compared to various MC simulations (curves). The ratios of MC simulations to the measurements are shown in the bottom panels. The inner error bars correspond to the statistical uncertainties, and the outer error bars represent the statistical and systematic uncertainties added in quadrature.

Measured (left panes) particle density, and (right panes) $\Sigma \pt$ density, in the transMAX and transMIN regions ($60\de < \abs{\Delta \varphi} < 120\de $, relative to the leading charged-particle jet in the event, with maximum/minimum UE activity), as a function of $\jetpt$. The definitions of the symbols and error bars are the same as for Fig.~\ref{fig:resultsTrans}.

Measured transDIF activity (see text for its definition) for (left) particle density, and (right) $\Sigma \pt$ density, as a function of $\jetpt$. The definitions of the symbols and error bars are the same as for Fig.~\ref{fig:resultsTrans}.

Comparison of UE activity at $\sqrt{s}= 0.9$, 2.76, and 7\TeV for (left) particle density, and (right) $\Sigma \pt$ density, as a function of $\jetpt$~\cite{UEleadjet, UEleadjet2}.
