approximation by the transverse energy of the select jet, hence the ratio of ${\ensuremath{p_{\mathrm{T}}}}(Z)/{\ensuremath{p_{\mathrm{T}}}}^{jet}$ should peak around 1. The comparison of data and MC of this ratio is also shown in Fig. \[fig:JetPerformance\], where a good agreement within the assigned systematic uncertainties can be seen. This study has been repeated in [@Apyan:2019ybx] with higher jet multiplicities and higher values of ${\ensuremath{p_{\mathrm{T}}}}(Z)$ in the final state, all indicating good closure.

Analysis Strategy, Signal Selection and Background Estimation\[sec:Analysis\]
=============================================================================

It is the goal of this analysis to probe a possible asymmetry between positive and negative values of $\alpha$ (defined in Section \[Sec:ParityViolation\]) in events containing at least three jets in proton-proton collisions at a center of mass energy of $\sqrt{s}=8$ TeV. The dependence of this asymmtry will be investigated in bins of the invariant di-jet mass of the leading and sub-leading jet, $m_{12}$. In addition, the normalized $\alpha$ distribution in data is measured and corrected for detector effects.

Events with at least three jets with a minimal transverse momentum of $p_T>$ 50 GeV within a rapidity range of $|y|<2.4$ are selected for this analysis. Events with a fourth jet with $p_T>30$ GeV within $|y|<3.0$ are vetoed. Standard noise cleaning cuts as well
