LHeC/QCDE-1 stage First of all, let us consider p$_{T}$ and η distributions for signal and background processes in order to determine appropriate kinematical cuts. Transverse momentum distribution of final state jets for signal at Λ = 10 TeV and background is shown in Fig. 5. It is seen that p$_{T}$ > 150 GeV cut essentially reduces background, whereas signal is almost unaffected. Figs. 6 and 7 represent pseudo-rapidity ( η ) distributions for electrons and jets, respectively. As seen from figure 7, η$_{e}$ − distribution for signal and background are not drastically different. 5 10 -2 10 0 10 2 10 4 10 6  400  600  800  1000  1200  1400  1600  1800  2000 (pb) M$_{e8}$(GeV) s=1.98 TeV =M$_{e8}$ =10TeV 10 -2 10 0 10 2 10 4 10 6  500  1000  1500  2000  2500  3000  3500 (pb) M$_{e8}$(GeV) s=3.74 TeV =Me8 =10 TeV
